autoconf: fix python2 checking and jons>=0.11

* Try to locate python in the sequence of:
python2.7 python 2.6 python2 python
Then check python version as we only support python 2.

* Pkconfig will try 'json.pc' if 'json-c.pc' failed.

Tested by OBS.
Manually tested by './configure && make check' on:
* Archlinux
* Fedora 20
* RHEL 6.5
* RHEL 7.0
