Erick Reyes 5a744684c3 libmeminfo: librank optimization using maps instead of vectors 
librank was calling std::vector::find_if in nested loops when iterating
through processes and maps.

Changed the implementation to use std::map::insert, this resulted in
a significant improvement to execution speed.

Test: time librank on crosshatch

Before:  1m22.57s real     1m15.87s user     0m05.79s system
After:   0m03.85s real     0m00.88s user     0m02.92s system
