[patch]: testsuite: run bash instead of sh when using brace expansion

[Christian Groessler <chris@groessler.org>]

Hi,

I had some testsuite failures in gdb.dwarf2/dw2-dir-file-name.exp, 
because /bin/sh on my system doesn't support brace expansion.
I'm using Debian, where /bin/sh is in fact dash. I tried /bin/sh on 
Solaris (9), too, and it also doesn't support brace expansion.

This patch changes dw2-dir-file-name.exp to use bash instead of sh.

Ok to commit?

regards,
chris

        * gdb.dwarf2/dw2-dir-file-name.exp: Use bash instead of sh, since
        brace expansion is not available in sh.
