perf test: Implement skip_reason callback for watchpoint tests
Currently reason for skipping the read only watchpoint test is only seen
when running in verbose mode:
$ perf test watchpoint
23: Watchpoint :
23.1: Read Only Watchpoint : Skip
23.2: Write Only Watchpoint : Ok
23.3: Read / Write Watchpoint : Ok
23.4: Modify Watchpoint : Ok
$ perf test -v watchpoint
23: Watchpoint :
23.1: Read Only Watchpoint :
--- start ---
test child forked, pid 60204
Hardware does not support read only watchpoints.
test child finished with -2
Implement skip_reason callback for the watchpoint tests, so that it's
easy to see reason why the test is skipped:
$ perf test watchpoint
23: Watchpoint :
23.1: Read Only Watchpoint : Skip (missing hardware support)
23.2: Write Only Watchpoint : Ok
23.3: Read / Write Watchpoint : Ok
23.4: Modify Watchpoint : Ok
