Do not attempt to update EFI boot in containers.

Browse Source 
Containers (at least many fo them) will bind-mount /sys which works for most
cases but it means that /sys will indicate EFI boot when it is, in fact, the
host system that has EFI boot.  To fix this we use systemd-detect-virt to see if
we're running in a container and if so we don't attempt to update EFI boot.
