CTest: Improve Python coverage.py source file search algorithm 

If the coverage.py source file is not found in the source directory, the
build directory is first searched before raising an error.

This is necessary because it is a valid workflow to build a Python
package from source, then install this package to a virtualenv that
lives in the build directory.  Tests will run against this deployed
package and therefore the covered source files will be found in a
subdirectory of the build directory, and not anywhere in the source
directory.
