[patch] Fix identical PASS in gdb.base/skip.exp

[Yao Qi <yao at codesourcery dot com>]

When I was looking at the FAILs in gdb.base/skip.exp, I found there are
some identical PASS in gdb.base/skip.exp.

      2 PASS: gdb.base/skip.exp: info skip
      2 PASS: gdb.base/skip.exp: skip
      2 PASS: gdb.base/skip.exp: skip file
      2 PASS: gdb.base/skip.exp: step after deleting 1 (1)
      2 PASS: gdb.base/skip.exp: step after deleting 1 (2)
      5 PASS: gdb.base/skip.exp: step

This patch is to fix this.  OK to apply?
