Compat fix for HHVM on non-Linux OSs

RUSAGE_THREAD is not POSIX; it's Linux-specific. HHVM now compiles on OS X,
and calling getrusage( 2 ) on OS X explodes with:

    exception : f_getrusage is not supported: RUSAGE_THREAD is not defined on
    this sytem [sic]

HHVM is being ported to Windows, too, where RUSAGE_THREAD is likewise missing.
So check that PHP_OS === 'Linux' before using it.
