passenger memory stats no longer have a total RSS

[micah]

The memory stats plugin is looking for this regexp in the output of
passenger-memory-stats:

stats =~ /RSS:\s_([\d.]+)\s_MB\Z/m

but the output of passenger-memory-stats has this:

Version: 4.0.53

At the very end of the output, in both Passenger 4 and 5, should be this:

### Processes: 4
### Total private dirty RSS: 79.95 MB

This is what it's parsing, and it works for me in both versions (on my fork). Maybe you missed the couple lines at the end of the output.
