[PATCH] installer: use /run for abort trigger and drop systemd-tmpfs-tmp

["'Badrikesh Prusty' via isar-users" <isar-users@googlegroups.com>]

Switch unattended abort trigger from /tmp to /run to rely on default
tmpfs.

Drop the systemd-tmpfs-tmp recipe and dependency, removing custom
tmp.mount setup as it is no longer needed.
