define PR_SET_MM_MAP & friends if necessary

PR_SET_MM_MAP only went in to the kernel at 3.18 (or 3.19), so we need to define these for kernels before then. If there was an error, the code simply logs the failure and continues on. Also, we can drop the PR_SET_MM_otherstuff contstants since those were dropped in 93525c00.
