catalyst: Remove mount_safety_check()
mount_safety_check() exists to prevent bad things from happening if a
previous catalyst invocation left bind mounts active in the chroot.
E.g., a previous catalyst invocation is interrupted without unmounting
the bind mounts. A new catalyst invocation runs and cleans the old
chroot, which inadvertently deletes files outside of the chroot via the
bind mounts.
With all the mounts now inside a namespace, it is no longer possible to
have mounts accessible outside the build sequence. In fact, I think this
code has been unnecessary since commit e5a53e42 ("catalyst: create
namespaces for building").
