Add package for jq

Disabling selinux
Fixes #146 

This adds jq (1.5) which is a command line filter for processing JSON. Configure warns about missing Ruby dependencies which I'm ignoring since we don't have proper manpage support yet and I don't see a need for bringing in additional bloat when disk space is limited for us to begin with. Also, regex support requires oniguruma which will come shortly.

Tested sucessfully on Samsung Chromebook 3 (XE500C13-K01US).

This adds libffi (3.0.13) which provides a portable foreign-function interface library. I'm adding this in preparation for an update to the newLISP package adding ffi and proper readline support which will enhance usability of the REPL and allow use of the GUI library if you install Oracle's JRE.
