[PATCH] gdb/testsuite: fix regexp in gdb.rocm/watchpoint-at-end-of-shader.exp

[Tankut Baris Aktemur <tankutbaris.aktemur@amd.com>]

The following tests fail:

  FAIL: gdb.rocm/watchpoint-at-end-of-shader.exp: precise_memory=on: continue
  FAIL: gdb.rocm/watchpoint-at-end-of-shader.exp: precise_memory=off: continue

The reason is a difference in outputs seen in upstream and downstream
branches.  Fix the regexps to avoid the failures.
