benchtests: Improve readability of JSON output

Add a small library to print JSON values and use it to improve the
readability of the benchmark output and the readability of the
benchmark code.

ChangeLog:

2014-04-11  Will Newton  <will.newton@linaro.org>

	* benchtests/Makefile (extra-objs): Add json-lib.o.
	(bench-func): Tidy up JSON output.
	* benchtests/bench-skeleton.c: Include json-lib.h.
	(main): Use JSON library functions to do output of
	benchmark results.
	* benchtests/bench-timing-type.c (main): Output the
	timing type simply, leaving formatting to the user.
