Adds explicit CC="distcc gcc" / CXX="distcc g++" to firefox-fourier/mozconfig, gated on /usr/lib/distcc/bin being in $PATH. Mirrors the pattern in ffmpeg-v4l2-request-fourier.

Without the explicit export, mach configure ignored the distcc wrappers and built locally despite BUILDENV=(distcc ...) on fermi.

pkgrel bumped so a rebuild publishes a new pkg. Output binary unchanged; only build-process change.

Companion to #32 (qt6 epoch fix) and PR-stream for firefox-fourier-debian build kickoff happening in parallel.

firefox-fourier: explicit CC/CXX=distcc in mozconfig f34bfa54b8 
fermi's makepkg.conf already has BUILDENV=(distcc ...) which prepends
/usr/lib/distcc/bin to PATH at build time. But Mozilla's mach
configure picks CC/CXX from the environment directly — it doesn't
treat the distcc shim in PATH as the default C compiler unless the
env vars are set explicitly. Without this guard the distcc workers
sat idle while mach drove a local-only build.

Mirrors the explicit-distcc pattern already used in
ffmpeg-v4l2-request-fourier/PKGBUILD.

Caveat documented in the comment: only the C/C++ portion
distributes. rustc and host-only build steps stay local. Empirical
~30-40% wall-clock improvement on a 4-worker pool (tesla, dcc1, dcc2,
ampere via Avahi zeroconf).

pkgrel bumped so a rebuild publishes a new package even though the
binary output for users is unchanged (build process speedup only).
