[PATCH] MAINTAINERS: fix regex pattern in CORE MM category

[Pedro Falcato]

The pattern "include/linux/page[-_]*" matches every file that starts with
"page", because it's a regex and not a glob (so it has the meaning of
include/linux/page + match [-_] 0+ times).

Fix it up into a more regex-correct expression. Doing so reduces CC's
drastically in patches that touch pagemap.h (which is maintained as part of
PAGE CACHE).

As a side-effect, move linux/pageblock-flags.h explicitly under PAGE
ALLOCATOR.
