Make wpa_supplicant work with uClibc 0.9.29.

This replaces an epoll_create1 call with an equivalent epoll_create
call.  epoll_create1 is not implemented before uClibc 0.9.32.

From the man page:  When the flags argument to epoll_create1 is 0, it
is equivalent to epoll_create.  epoll_create's argument is ignored,
but must be > 0.
