Build art_Framework_Services_FileServiceInterfaces

Provide minimal build of art_Framework_Services_FileServiceInterfaces
library. Add library and define include/link interfaces,installing
headers and library to standard locations.

NB: link to FNALCore likely to be interface only as it appears objects
only appear in headers of art_Framework_Services_FileServiceInterfaces.
Therefore may not need to link directly, only provide as part of
link interface.
