configure: Support libsctp < 1.0.17 without libsctp.pc
libsctp 1.0.17 is the first to contain a pkgconfig file in upstream.
Current OpenSure Leap 15.3 as well as our OpenEmbedded meta-telephony
layer still ship 1.0.16 which contain no pkgconfig file.
Let's attempt first finding the .pc file, and otherwise manually link
against the lib.
