main/postmarketos-base: retire devmappings service (MR 1820)

Remove devmappings service. The original purpose of this service was to
ensure that /boot is mounted properly after the initramfs passed control
to OpenRC, because the initramfs used to umount /boot before that. With
/etc/fstab alone, /boot get not get mounted with subpartitions (which we
use on Android devices), if util-linux >= 2.33 was installed (MR 115).

Nowadays, we don't umount /boot in the initramfs before passing control
to OpenRC anymore (MR 1398). So this service isn't needed anymore, and
prevented the previous pmOS_inst_boot <> pmOS_boot patch from working
correctly.
