libbacktrace: Suppress the default action-if-found for AC_CHECK_LIBS.

Zlib is not a dependency of libbacktrace, and so it shouldn't be added
to LIBS.

libbacktrace/

* configure.ac: Move define of HAVE_ZLIB into check for -lz.
* Makefile.in: Regenerate.
* config.h.in: Likewise.
* configure: Likewise.
