gluster-block: migrate build to libtoolz and create rpm

Till now we had simple makefile for checking dependencies and building.

Using libtoolz will give more control on dependency checks and
flexibility.

This patch also introduce rpm build feature.

Compiling:
$ ./autogen.sh
$ ./configure
$ make -j
$ make install

Building RPMS:
$ make rpms

Running:
$ systemctl start gluster-blockd.service

Using CLI:
$ gluster-block help
