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
