configure: Add autoconf check for libopus.

Because opus transcoding support cannot be included in the standard Asterisk distribution, a few codec_opus implementations have popped up. To make it easier for people to drop in opus support in their own installations, this patch adds configure checks for libopus. Review: https://reviewboard.asterisk.org/r/4106/ git-svn-id: https://origsvn.digium.com/svn/asterisk/branches/13@426234 65c4cc65-6c06-0410-ace0-fbb531ad65f3
