[gvfs] gvfs-test: Fix for Python 3.3

commit 9fcbba900c87a41a85281bec3ee1989258f3a3db

    gvfs-test: Fix for Python 3.3
    
    Use read() instead of readall() for reading from subprocess, as this is a
    BufferedReader() now. This also works for older Python versions.
    
    Also, add another missing Popen.stdin.flush(), like in the previous commit.
