fix(ci): install only makedepends, skip full depends via -d

moonarch-git's runtime depends include AUR-only packages (stasis,
auto-cpufreq, ttf-ubuntusans-nerd) that plain pacman cannot resolve,
so `makepkg -s` fails with "Could not resolve all dependencies" —
even though those runtime deps aren't needed to build the package.

Extract makedepends from PKGBUILD, install them targeted (cargo/go
for Rust and Go packages; empty for moonarch-git), then run makepkg
with -d so it skips the full dep check. Rust packages still get their
compiler, moonarch-git builds without needing the AUR world.
