Build and install libafsrpc.so.2

During the libtool interim, we had been building a .0 but not
installing it.  Prior to the libtoolization of shlibafsrpc, we
had installed a libafsrpc.so.1.4 (though the 1.6 branch was
installing libafsrpc.so.1.5, "so we don't collide with the shlibafsrpc
versions on the master branch", which seems misguided).  Since there
have been backwards-incompatible ABI changes (e.g., rx_SetMaxMTU) since
the .1.4 version, we must bump the SONAME to .2.0.

At time of this writing, the libtool rules for updating the
version information is found at:
http://www.gnu.org/software/libtool/manual/html_node/Updating-version-info.html
and
http://www.gnu.org/software/libtool/manual/html_node/Libtool-versioning.html

This lets us consolidate the building of the shared and static libafsrpc
and their installation), as libtool will happily do both for us
at once.

We explicitly do not install the .la files, as our libtool use is
to be kept entirely internal.
