kernel/vm: Add "unmergeable" flag to VMCache.

ramfs needs to create caches that are both temporary and unmergeable, so add another flag to make this state possible. Otherwise, mmap'ed files from ramfs might wind up in VMCache trying to merge the caches when the last one is closed, which we don't want.
