fix Issue 22816 - [REG 2.099] Parser reads files with other extensions

[ibuclaw]

I can't see any rationale for this looking up filenames with different extensions. Either Module.read or the driver already ensures that the filename already has an inferred extension for all file arguments from the command-line.

All other uses of FileManager.lookup in dmd.error and dmd.expressionsem will also either have a file extension or have been checked that it exists on disk before calling.

No idea how to test this - I guess using dshell? It's important not to delay getting this in though, as it should not hit a release.

Create fail_compilation/extra-files/foo.c + a fail_compilation test with EXTRA_SOURCES: extra-files/foo.d ?

That's not really friendly with the dejagnu scripts, which expect these test directives to be pointing to files that exist. ;-)
