Bug 1865969 - Remove architecture allowlist on VA-API support. r=stransky,media-playback-reviewers

Since libva is platform-agnostic and loaded at runtime, there's no harm enabling
it on all platforms running Linux.

This patch has been tested locally on amd64, arm64, ppc64el, mips64el and
loongarch64.
