build: add --without-server option

With Gluster 4.0 we will not provide the server components for EL6 and
older. At one point Gluster 4.x will get GlusterD2, which requires
Golang tools in the distribution. EL6 does not contain these at the
moment.

With this change, it is possible to `./configure --without-server` which
prevents building glusterd and the xlators for the bricks. Building RPMs
can pass `--without server` and the glusterfs-server sub-package will
not be created.
