Subject: [PATCH] configure.ac: fix build with openssl

- Add a call to PKG_CHECK_MODULES to get openssl libraries and its
  dependencies if openssl support is enabled
- Add OPENSSL_LIBS to libupnp.pc.in so that applications linking with
  pupnp (such as mpd) will be able to retrieve openssl libraries

Fixes:
 - http://autobuild.buildroot.org/results/a4148e516070b79816769f3443fc24d6d8192073
