core/mount: Don't unmount initramfs mounts
A mount within /run/initramfs is indicative that the mount was
created by initramfs init and will be unmounted by initramfs
shutdown.
It is unlikely that such a mount point would even be unmountable
by the the main system, for example in the case of the root file-
system being loop-mounted from a file in a /run/initramfs mount.
