Revert "Use allocation granularity as the 'page_size' in /proc/<pid>/status as well, for consistency with /proc/<pid>/statm"

This reverts commit 8a32c24a7bdb0f3d80daa8f267cc63d15edcf771.

Replacing page_size() with allocation_granularity() was incorrect.
The values returned by get_mem_values() are # of pages of size
page_size(). Multiplying with allocation_granularity() here
results in values 16 times too big.
