[Skiboot] [PATCH 02/13] test/mem_region: fix incorrect ibm, os-reserve region length

[Stewart Smith]

We were reserving all of memory up to the heap, which is fine
*unless* the system libc chooses to allocate something in that
block of memory that we use, which means we have overlapping
regions and general pain.

This should fix failing unit tests on some systems (e.g. Debian)
