[lldb][test][NFC] TestBreakpointSetRestart.py: split up assertion to determine which check specifically fails in CI

This test consistently fails on the public macOS ASAN CI (and isn't
reproducible locally):
```
FAIL: test_breakpoint_set_restart_dwarf
(TestBreakpointSetRestart.BreakpointSetRestart)
----------------------------------------------------------------------
Traceback (most recent call last):

    self.assertTrue(bp.IsValid() and bp.GetNumLocations() == 1,
VALID_BREAKPOINT)
AssertionError: False is not true : Got a valid breakpoint
```

From this error we're not quite sure what about the breakpoint here is
the problem.

This patch splits up the assertion to narrow down the issue.
