[PATCH] selftests/mm: Fix mseal's length

[Pedro Falcato]

We accidentally msealed too much, which could overrun and try to mseal
other regions. This seems to be harmless (at least on top-down
architectures) due to various reasons all aligning, but may very well
cause spurious test failures to e.g bottom-up mmap architectures.
