run-tests: print more information on unnecessary glob matching
Extend the message with the test name and the approximate line number. (The
line number is the one of the command producing the output.)
Finding the line to fix is easier now.
old message:
......
Info, unnecessary glob: at a/b/c (glob)
..
new message:
......
Info, unnecessary glob in test-example.t (after line 9): at a/b/c (glob)
..
The test result is still pass as before.
