t5501-old-fetch-and-upload.sh fails with NO_PYTHON=1

Hello,

t/t5501-old-fetch-and-upload.sh fails on Solaris 9 with NO_PYTHON=1.
The test doesn't work correctly on Linux with NO_PYTHON=1, too, but it
doesn't cause a failure there.

When NO_PYTHON=1 is set, t/Makefile passes "--no-python" to the test as
an argument.  That causes the $list variable to be set to "--no-python"
instead of "fetch upload".  Since that string does not identify a
program to be tested, $pgm remains unset.

On Linux the return code of "which $pgm" is 1 in that case, which
causes the test to do nothing and exit without failure.  In contrast,
the return code of "which" without any argument is 0 on Solaris, so
the test is being run and fails.

I have attached a simple fix, but is this test still useful at all?

Regards,
Dennis
