    build: Remove unnecessary vala language dependency
    
    (cherry-picked from e4a71d9cff6002d5d62e417d43241dbdbb3e2d54)
    tracker-miners doesn't use any vala, but due to vala declared as
    a used language it does error out if valac isn't found. Remove the
    language and unused vapi helper variable.
