    gdb/testsuite: resolve duplicate test names in gdb.threads/tls.exp
    
    While running the gdb.threads/tls.exp test with a GDB configured
    without Python, I noticed some duplicate test names.
    
    This is caused by a call to skip_python_tests that is within a proc
    that is called multiple times by the test script.  Each call to
    skip_python_tests results in a call to 'unsupported', and this causes
    the duplicate test names.
    
    After this commit we now call skip_python_tests just once and place
    the result into a variable.  Now, instead of calling skip_python_tests
    multiple times, we just check the variable.
    
    There should be no change in what is tested after this commit.
