From: Daniel P. Berrange <berrange@xxxxxxxxxx>
Always generate the rpc files, and require rpcgen during bootstrap.
* daemon/Makefile.am: Removed generated files with
maintainer-clean target
* src/Makefile.am: Removed generated files with
maintainer-clean target. Always run 'rpcgen' if
generated files are missing
