This rearranges bootctl a bit, so that it uses the usual verbs parsing routines, and automatically searches the ESP in /boot, /efi or /boot/efi, thus increasing compatibility with mainstream distros that insist on /boot/efi. This also adds minimal support for running bootctl in a container environment: when run inside a container verification of the ESP via raw block device access, trusting the container manager to mount the ESP correctly. Moreover, EFI variables are not accessed when running in the container.
