fix(ci): disambiguate sccache binary for ubi backend on x86_64

ubi:mozilla/sccache picks sccache-dist instead of sccache on x86_64
linux because both release assets match the platform and ubi selects
sccache-dist first alphabetically. The sccache-dist binary is the
distributed build scheduler, not the compiler cache wrapper, causing
RUSTC_WRAPPER to fail with 'unrecognized subcommand'.

Use matching="sccache-v" to filter release assets at download time,
ensuring ubi selects sccache-v0.14.0-* instead of sccache-dist-v0.14.0-*.
The exe option alone is insufficient because ubi partial-matches
sccache-dist containing sccache. arm64 is unaffected since sccache-dist
has no arm64 release asset.
