[PATCH v4 3/4] Change GIT_ALLOC_LIMIT check to use ssize_t for consistency

[Steffen Prohaska <prohaska@zib.de>]

GIT_ALLOC_LIMIT limits xmalloc()'s size, which is of type size_t.  Use
ssize_t to store the limit for consistency.  The change has no direct
practical impact, because we use GIT_ALLOC_LIMIT to test small sizes.

The cast of size in the call to die() is changed to uintmax_t to match
the format string PRIuMAX.
