Added packaging dir and .spec and .manifest files

Created buxton-simp.spec and buxton-simp.manifest using the buxton
spec and manifest files as a template.
Fixed .spec file

The .spec file now makes an rpm, but it still has some problems.
TODO: fix  the manifest problem; find out where buxton.service,
buxton.socket, and sockets.target.wants are being installed or make
them be installed where they are expected
Fixed spec file to find buxton.service and buxton.socket files

Added a line to install the buxton files in the systemd folder, and
uncommented the lines to add them to %file. Moved some files to devel.
Commented out manifest and requires lines, to be added back in when
building the rpm with tizen.
Deleted output file in packaging
