build: only add 'serial-tests' for automake >= 1.12.
This patch is based on the following patch written by Richard W.M. Jones
from RedHat:
https://www.redhat.com/archives/libguestfs/2013-February/msg00102.html
Earlier versions of automake complain if they get a configuration
parameter which they don't understand. The error is:
configure.ac:27: error: option 'serial-tests' not recognized
Use some m4 hackery to work around this.
