Thiébaud Weksteen 8ec690764e Fix ReplaceExtension
ReplaceExtension had an unexpected behaviour when the file did not have
an extension. In certain cases, the final path would be severely
trimmed: out/.intermediates/my_file would become out/.new_extension.
Explicitly handle the case by appending the new extension.

Test: Run checkbuild on Android Soong
