[analyzer] Fix -x language argument for C preprocessed sources

clang's -x option doesn't accept c-cpp-output as a language (even though
463eb6ab was merged, the driver still doesn't handle that).

This bug prevents testing C language projects when ccache is used.

Fixes #25851.

Investigation and patch by Dave Rigby.
