FYI: do not include full file names in test names

[Tom Tromey]

I'm checking this in.

While digging through gdb.sum diffs, I noticed a couple of places where
a file name appears in a test name, e.g.:

PASS: gdb.python/python.exp: source ../../../archer/gdb/testsuite/gdb.python/source2.py

This yields spurious differences if you do builds in different
directories.

This patch changes the tests to have location-independent names.

	* gdb.base/source.exp: Don't include full file name in test name.
	* gdb.python/python.exp: Don't include full file name in test
	name.
