Subject: configure.ac: add --enable-sanitize

Add --enable-sanitize to ./configure, as a copy-paste from libosmocore.

When building libosmocore with --enable-sanitize, osmo-sip-connector cannot be
linked if it doesn't include asan as well.

This is particularly annoying to me when using sanitize.opts in osmo-dev. I'd
have to turn off *all* asan everywhere just to include the osmo-sip-connector
dep that was recently added.
