Lennart Poettering 2f2c539cd4 bootctl: rework to use common verbs parsing, and add searching of ESP path
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.

<para><command>bootctl</command> checks, updates,
installs or removes the boot loader from the current
system.</para>
<para><command>bootctl status</command> checks and prints the
currently installed versions of the boot loader binaries and
all current EFI boot variables.</para>
<para><command>bootctl update</command> updates all installed
versions of systemd-boot, if the current version is newer than the
version installed in the EFI system partition. This also includes
the EFI default/fallback loader at /EFI/BOOT/BOOT*.EFI. A
systemd-boot entry in the EFI boot variables is created if there
is no current entry. The created entry will be added to the end of
the boot order list.</para>
<para><command>bootctl install</command> installs systemd-boot into
the EFI system partition. A copy of systemd-boot will be stored as
the EFI default/fallback loader at /EFI/BOOT/BOOT*.EFI. A systemd-boot
entry in the EFI boot variables is created and added to the top
of the boot order list.</para>
<para><command>bootctl remove</command> removes all installed
versions of systemd-boot from the EFI system partition, and removes
systemd-boot from the EFI boot variables.</para>
<para>If no command is passed, <command>status</command> is
implied.</para>
