Fix compilation with jemalloc on macos

Browse Source 
On darwin we avoid including sys/user.h to avoid a conflict. Previously
we still ended up with PAGE_SIZE being defined because the headers for
system malloc define it. However, when compiling with jemalloc nothing
would define PAGE_SIZE.

This commit changes configure.ac so that we never use the PAGE_SIZE
constant on darwin and to always use the sysconf fallback.
