Subject: [PATCH] Modify configure to prevent unnecessary kqueue checks

By only running the TORRENT_CHECK_KQUEUE_SOCKET_ONLY check if kqueue support
is already detected, we increase the number of platforms that we can
cross compile on.
Otherwise, the cross compilation fails due to TORRENT_CHECK_KQUEUE_SOCKET_ONLY
using AC_RUN_IFELSE, which fails during cross compilation.
