Add .x86_64 and _amd64 suffixes to .rpm and .debs

Also:
* update README documentation
* correct postinst scripts for deb and rpm
* add lib64/ to link_directories (needed for CentOS and others)
* remove a redundant "rdc" from the package names
* rearrange the package names to conform to convention
For example:
rdc-server_1.0.0.0.local-build-0-c3187fb-dirty_amd64.deb
rdc-server_1.0.0.0.local-build-0-c3187fb-dirty.x86_64.rpm

* fix issues that result from having, in essence, 2 different
  install prefixes, 1 for the client and 1 for the server.
