Douglas Teles a5b1862117 FHS F2.1: mesa_shader_cache -> /var/cache/mesa ...

First migration of the Class C cache work: the Mesa shader cache moves
from the LibreELEC-style /storage/.cache/mesa_shader_cache to the
Arch-standard /var/cache/mesa.

Implementation follows the bridge-symlink pattern systemd already uses
for /etc/*: the archr meta-package creates /var/cache/mesa as a
build-time symlink into /storage/.cache/mesa_shader_cache. Mesa,
runemu.sh and any inspector see the FHS path; writes still land on the
storage overlay so the cache survives reboots.

archr/package.mk: mkdir /var/cache, ln -sf the symlink.

quirks/profile.d/041-panfrost: MESA_SHADER_CACHE_DIR=/var/cache/mesa.
Comment explains the bridge so future readers do not assume tmpfs.

runemu.sh: create the cache dir through /var/cache/mesa instead of
the legacy /storage path. Comment updated to mention the symlink.

systemd/tmpfiles.d/z_01_archr.conf is intentionally left targeting the
backing path /storage/.cache/mesa_shader_cache: it is internal plumbing
that must guarantee the real overlay dir exists; /var/cache/mesa is
the surface, /storage/.cache/mesa_shader_cache stays the substrate.
