[PATCH] Tighten regexp in gdb.base/setshow.exp

["Andrew Burgess" <aburgess@broadcom.com>]

Had a random test failure in gdb.base/setshow.exp caused by $gdb_prompt
not being used on the end of a regexp for gdb_test_multiple.

Fixed in the two obvious places.  Other uses of gdb_test_multiple in
this file are messing with the prompt so I've left them alone.

OK to apply?

Thanks,
Andrew
