[PATCH] kernel32: implement GetLargePageMinimum

[Marcus Meissner]

From: Austin English <austinenglish at gmail.com>

https://bugs.winehq.org/show_bug.cgi?id=18745

Report 2MB minimum page size on i386.

This assumes that all x86 processors and the 64/32bit emulation mode
have hugetable support and it is always enabled.
