Consolidate three single-target config hooks into one

Merge journald-improve, logind-improve and remove-community-in-pacman
into biglinux-improve-compatibility-config.hook. All three fired on
biglinux-improve-compatibility install/upgrade only, each spawning a
separate /bin/sh + sed chain. Running them from a single Exec reduces
pacman hook fork overhead on our package upgrades without changing
behavior or trigger frequency.

No functional change: the same idempotent sed edits apply to
/etc/systemd/journald.conf, /etc/systemd/logind.conf and
/etc/pacman.conf.
