linuxrc: Refactor switch_root error handling
Previous idea (commit 93bf318e5114233f3cacc4575ab2e58d60e785c7) never
worked: Exec will replace initramfs' init (PID 1) with specified command
so that any further line will never be reached. If that command will
fail now, init basically ended which will trigger a kernel panic:
!! A fatal error has occured since /sbin/openrc-init did not
!! boot correctly. Trying to open a shell ...
+ exec /bin/bash
/init: exec: line 1366: /bin/bash: not found
[ 55.060649] Kernel panic - not syncing: Attempted to kill init! exitcode=0x00007f00
The new error handling will keep init running in loop which will
allow user to fix every detected problem until we are confident that
switch_root call has a chance to succeed.
In case the user cannot fix the problem (maybe because of
gk.userinteraction.disabled), we will call the newly added
gk.emergency action (reboot, poweroff or halt).

defaults/config.sh: Use --buildpkg=n and --usepkg=n in DEFAULT_MODULEREBUILD_CMD
While we call emerge with "--ignore-default-opts" since commit da5a5fa797a5fffa6c4d694cbfe2edc83bab4890
to avoid conflicting emerge options, we also need to ensure that
we don't clash with problematic emerge FEATURES like "getbinpkg".

linuxrc: Load network modules only when needed
To avoid problems related to drivers requiring special firmware which
might be not available when loading the module because the user don't really
need that module but it was added based on genkernel's module_load file,
we will no longer load network modules on boot.
Instead we will only load network modules when needed, for example
when dosshd is set or NFS is used.

Add option to force importing zpool using cache
Add simple option to pass to kernel via loader.
dozfs=cache will use /etc/zfs/zpool.cache
avoiding 30+ second wait for udev in zpool import
Also it's possible to use both cache and force
at the same time:
dozfs=force,cache (order is not important) will
force import and use cache.
Closes: https://bugs.gentoo.org/627320

linuxrc: use "quiet" cmdline argument for a really quiet initramfs initialization
"quiet" is already used by the kernel to avoid printing messages on the
console unless they are errors or warnings. Genkernel should do the same
wrt its initramfs initialization code.
This has also the advantage of improving the boot speed.

Drop doslowusb and noslowusb boot parameters.
scandelay=<secs> should be always preferred. Moreover, nowadays
automatically sleeping waiting for USB storage to come up in
the way we were used to do it doesn't work as one expects, because
USB is very common and USB storage devices are very likely to be
present on a system.
Furthermore, the initialization code after setup_slowusb is already
waiting for devices to come up.
