BUG/MINOR: pool/stats: Use ullong to report total pool usage in bytes in stats

The same change was already performed for the cli. The stats applet and the
prometheus exporter are also concerned. Both use the stats API and rely on
pool functions to get total pool usage in bytes. pool_total_allocated() and
pool_total_used() must return 64 bits unsigned integer to avoid any wrapping
around 4G.

This may be backported to all versions.
