hiredis: Add recipe

Hiredis is a C client library for Redis database.
Hiredis does not use autotools, but plane Makefile instead,
so few changes had to be made, including removing hard coded
compiler, setting INSTALL to 'cp -r' to to avoid host user
comtamination QA issue, and setting PREFIX to ${prefix} instead of
default /usr/local.
