[PATCH 2/2] create the `totals' rculfhash as early as possible

[Eric Wong <mwrap-perl@80x24.org>]

This allows us to start tracking allocations before Perl calls
our BOOT code, which can be far later if it has to boot other
modules first.  As an LD_PRELOAD, the constructor can fire
before Perl's main().
