    build: Remove unnecessary timerfd check variable
    
    The `HAVE_TIMERFD` define should only be set when the test code
    compiles. When the code compiles we can ensure that
    `HAVE_TIMERFD` has to be unconditionally defined, so the auxiliary
    `have_timerfd` variable used for this is unnecessary.
