README update to the local Arch package source. PKGBUILD
unchanged — still applies 0001 (the diagnostic bypass).
The 0002 patch (poll dmabuf fd directly, drop the
EXPORT_SYNC_FILE + sync_file roundtrip) is staged for
validation; when validated, swap the source array entry in
PKGBUILD from 0001 to 0002 and rebuild.
