MADV_PAGEOUT, MADV_POPULATE_READ, MADV_COLLAPSE are conditionally defined as necessary. However, that was being done in .c files, and a new build failure came up that would have been automatically avoided had these been in a common header file. So consolidate and move them all to vm_util.h, which fixes the build failure.
