Reorganize directory structure

Moving to directory per-application layout.  This facilitates
building single applications which is useful in the Yocto build
environment since different applications satisfy different OpenBMC
build requirements.

A number of issues are also addressed:
 - All applications were pulling in libsystemd and the gdbus libs
    irrespective of whether or not they were needed.
 - gpio.o duplicated in every application - moved to libopenbmc_intf
 - Added install target
