Ensure efivarfs is mounted in the chroot when running the installer.

If the efivarfs was already mounted in the installer runtime environment,
the previous code would detect that and not mount it in the installed
system enviroment. Currently this doesn't happen unless the user manually
mounts it, but protect against that and against future changes.
