Title: Add a linux rlimit /proc based fallback code

It turns out that the `prlimit` syscall is only available starting with
glibc 2.13, while some systems out there are much older. This commit
makes Process.rlimit() work for at least reading the limit, by reading
the file /proc//limits. Setting a new limit is not supported for
obvious reasons.
