Currently zbud pages do not have any flags set so it is not possible to
identify them during migration or compaction.
Implement PageZbud() by comparing page->_mapcount to -127 to distinguish
pages allocated by zbud. Just like PageBuddy() is implemented.

Usage of DTS macros instead of hard-coded numbers makes code easier to
read. One does not have to remember which value means pull-up/down or
