    timerfd: Expect periodic timer performance failures
    
    The current timerfd implementation fails to correctly count events on a
    nanosecond callout interval. The timerfd__periodic_timer_performance
    test detects this and reports failure.
    
    Mark this test as an expected failure so it isn't flagged by CI. A link
    to the bug report is attached to the test for reference.
    
    While we're here, clean up some minor style and Make issues.
    
    Fixes:          834c1ba793d9 ("timerfd: Add tests")
    MFC after:      1 week
    
    (cherry picked from commit cb692380f1e05ffc4184877844e93051f24ed302)
