Additional build system update for libefi library. This include updating all the Makefile.am to have the correct include paths and libraries. In addition, the zlib m4 macro was updated to more correctly integrate with the Makefiles. And I added two new macros libblkid and libuuid which will be needed by subsequent commits for blkid and uuid support respectively. The blkid support is optional, the uuid support is mandatory for libefi.
