rpm: reduce package dependencies and add -client-xlators

Restructuring the RPM packages in order to reduce the dependencies that
get installed for glusterfs-api (mainly on request for Qemu hosts).

The dependencies of these packages look roughly like this:

  .------------------.
  | glusterfs-server |
  '-------+----------'
          |\
          | \
          |  '---------------+--------------------.
          |                  |                    |
          |                  v                    v
          |         .----------------.     .---------------.
          |         | glusterfs-fuse |     | glusterfs-api |
          |         '--------+-------'     '------+--------'
          |                 /|                   /|
          |                / |                  / |
          |               /  |                 /  |
          |              /   |                /   |
          | .-----------+----=---------------'    |
          |/                 |                    |
          v                  v                    v
    .-----------.         .--------------------------.
    | glusterfs |         | glusterfs-client-xlators |
    '-----------'         '--------------------------'

With this structure, users can install glusterfs-server, glusterfs-fuse
or glusterfs-api (libgfapi) without getting any unneeded xlators or
other scripts/binaries.

The "glusterfs" and "glusterfsd" binary (symlinked) is now part of the
glusterfs-fuse package (moved from glusterfs). This does not make a
difference for glusterfs-server installations, because a server
installation always needs the glusterfs-fuse package for doing internal
mounts.

The advantage is that glusterfs-api does not pull in any executables
that get into the $PATH. This has caused confusion before when people
tried to remove the (wrongly assumed) server-only "glusterfsd" binaries.
