[committed][gdb/testsuite] Use $gdb_test_file_name in gdb.dwarf2

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

Hi,

In f.i. gdb.dwarf2/dw2-line-number-zero.exp we find:
...
    verbose "Skipping dw2-line-number-zero test."
...

Make the skip messages use the gdb_test_file_name variable, to reduce the
amount of changes that needs to be made when coping a test-case.

Tested on x86_64-linux.

Committed to trunk.

Thanks,
- Tom
