features/glupy: Add mem accounting support

When glusterfs is built from source using -DDEBUG flag and glupy
xlator is added to vol file, the brick process used to crash when
mounting the volume.

This fix is largely derived from the fix submitted for BZ #1035751.
Thanks to Justin Clift for helping in tracking this down.
