[committed][gdb/testsuite] Clean up redundant info in gdb.dwarf2

[Tom de Vries <tdevries@suse.de>]

Hi,

In gdb.dwarf2/ada-valprint-error.exp we find:
...
    untested ${testfile}.exp
...
such that we have:
...
UNTESTED: gdb.dwarf2/ada-valprint-error.exp: ada-valprint-error.exp
...

Fix this and a likewise unsupported message in
gdb.dwarf2/dw2-dir-file-name.exp.

Tested on x86_64-linux.

Committed to trunk.

Thanks,
- Tom
