[pygobject] Fix "distcheck" and tests with out-of-tree builds

[Martin Pitt <martinpitt src gnome org>]

commit 81de788a72b40acd2f857718d78bdeea01d12eb1

    Fix "distcheck" and tests with out-of-tree builds
    
    - Symlink *.py files from srcdir into builddir during build, as Python does not
      accept the extensions and modules in different paths.
    - "make clean" should remove *.pyc files
    - tests/runtests.py: Look for tests in srcdir, not in builddir
