sysconf: Support _SC_(AV)?PHYS_PAGES.
Do it by following the trail of the existing commented code, which implemented it by calling get_phys_pages() and get_avphys_pages(). This patch implements these two functions, which are also glibc extensions. Some program/libraries (e.g. libuv) assumes that sysconf(_SC_PHYS_PAGES) works on linux and never check for -1, thus they report an insane amount of memory.
