* Make the structure of the server pkg match 6.2.28
* Fix OSX lib path
* Fix install destinations in client
Previously, backup_agent would map to fdbmonitor installation dir -
which is incorrect in the sense that it disagrees with where the default
foundationdb.conf expects to find backup_agent. Add a new backupagent
installation dir and install there, matching foundationdb.conf's
expectations.
Also fix an issue where several of the versions of fdbbackup weren't
being installed
* Update packaging/osx/buildpkg.sh for cmake
* Update README instructions for pkg file
* Remove osx cpack config
* Remove pm install destinations
* Fix weird syntax
* Remove cpack reference to PM
* Address review comments
