fix-tests: fix when gtest outputs absolute source paths 

Since CMake 3.21, the Ninja generator now outputs absolute paths to
source files, rather than relative. These paths are what __FILE__ gets
mapped to during compilation, and is what gtest outputs for test
failures. This broke fix-tests, which assumed a build-relative source
path. This change detects when the source file path is absolute, and
converts it to a build-relative one.

Also, on Windows, absolute paths include the drive with a colon
character, so I added matching the colon to the regex for the path
portion.
