ci: repo-remove before repo-add so db CSIZE matches new build bytes

makepkg output isn't byte-deterministic across runs; same pkgver-pkgrel
rebuilds produce different .pkg.tar.xz bytes. repo-add no-ops on
same-version entries, leaving the db's CSIZE/SHA256 pointing at the
previous build while the nc copy is the new one — alpm then refuses
download with 'Maximum file size exceeded'. Force-remove first.
