uml: remove PAGE_SIZE from libc code
Distros seem to be removing PAGE_SIZE from asm/page.h. So, the libc side of UML should stop using it. I replace it with UM_KERN_PAGE_SIZE, which is defined to be the same as PAGE_SIZE on the kernel side of the house. I could also use getpagesize(), but it's more important that UML have the same value of PAGE_SIZE everywhere. It's conceivable that it could be built with a larger PAGE_SIZE, and use of getpagesize() would break that badly. PAGE_MASK got the same treatment, as it is closely tied to PAGE_SIZE.
