libsctp: Fix build and don't link everything to libsctp
On some systems sctp_* is part of the standard libc, so do not
use AC_CHECK_LIB but AC_SEARCH_LIBS to find the symbol we need.
Both macros modify LIBS which means all applications will link
again libsctp and this is not what we want. Undo the side-effect
of LIBS and export LIBSCTP_LIBS which is already used in the
Makefile.am.
