Bug#627532: allocator using mmap crashes on non-4k-page platforms

[Lifeng Sun <lifongsun@gmail.com>]

Package: apr
Version: 1.4.4-1
Severity: grave
Tags: patch

The code incorrectly presumes the page size will be always 4k, which
causes that it fails to pass the test suite on non-4k-page platforms.
The attached patch seems to work.

Lifeng
