[proc.txt] Fix /proc/pid/statm documentation

[Roger Luethi <rl@hellgate.ch>]

I really wanted /proc/pid/statm to die [1] and I still believe the
reasoning is valid. As it doesn't look like that is going to happen,
though, I offer this fix for the respective documentation.
Note: lrs/drs fields are switched.
