[third_party][spirv-tools] Make `:spvtools_build_version` hermetic

Bug:80983

The script in the `:spvtools_build_version` target reads the "CHANGES"
file as well as scans ".git/HEAD" (and the git directory) for tags.

Neither input was listed.

Listing the target's inputs in combination with fxrev.dev/557890 makes
the target hermetic.

Testability:

Successfully build locally with trace actions enabled or on the CQ.
