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
