Adjust spec file for tarball building
Adjust spec file for tarball building

We support building RPMs from a tarball, not directly from git (RPM
needs a tarball anyway, so requiring people to run make dist doesn't
seem onerous).

Remove autogen.sh invocation and remove explicit building of
documentation.  Both of these are done as part of make dist
