    Remove custom main() from test_PipeCapture (!22)
    
    After removing Glib::thread_init() from test_PipeCapture's main() all it
    does is exactly what the built in Google Test main() does [1][2].  So
    use that instead like the other unit test programs do.

    Closes !22 - Increase minimums to libparted 2.2 and glibmm 2.32
