Accounting for big-endian architectures in proc

The proc utils were assuming that encoded ip addresses were little-endian. This was fixed in the project these utils are based on (psutil) and I'm adopting the fix... https://code.google.com/p/psutil/issues/detail?id=201 https://trac.torproject.org/projects/tor/ticket/4777

This evidently occures on OpenWRT (ar71xx), thanks to swalker for the catch!
