    [gdb/testsuite] Fix gdb.rust/watch.exp on ppc64le
    
    On x86_64-linux, I have:
    ...
    (gdb) watch -location y^M
    Hardware watchpoint 2: -location y^M
    (gdb) PASS: gdb.rust/watch.exp: watch -location y
    ...
    but on powerpc64le-linux, I run into:
    ...
    (gdb) watch -location y^M
    Watchpoint 2: -location y^M
    (gdb) FAIL: gdb.rust/watch.exp: watch -location y
    ...
    due to the regexp matching "Hardware watchpoint" but not "Watchpoint":
    ...
    gdb_test "watch -location y" ".*watchpoint .* -location .*"
    ...
    
    Fix this by making the regexp less restrictive.
    
    Tested on x86_64-linux and powerpc64le-linux.
