Enable kqueue for APPLE targets

Browse Source 
The CMAKE_CROSSCOMPILING variable is not set for Apple targets seemingly
because of cmake implementation details (more info
https://cmake.org/cmake/help/latest/variable/CMAKE_CROSSCOMPILING.html).
Since Apple targets have working kqueue implementations this check makes
sure we enable it always when those are the targets, without users
having to explicitly set EVENT__HAVE_WORKING_KQUEUE
