make.globals: make FEATURES=-binpkg-multi-instance sticky for existing installs
Add a _compat_upgrade.binpkg_multi_instance script that the ebuild
can call in pkg_preinst in order to maintain a backward-compatible
FEATURES=-binpkg-multi-instance default on existing installs where
enabling binpkg-multi-instance could cause disruption.
