ssh kitten: Support system where the login shell is a non-POSIX shell

Browse source 
Now the kitten passes its script to /bin/sh and detects the login shell
using various strategies based on the value of $USER on the remote
machine. The strategies are tried one after another till one succeeds:

1) getent passwd $USER
2) id -P
3) python pwd module
4) parsing /etc/passwd

The hope is that these strategies will fail on fewer systems than
relying on the login shell being POSIX compliant.
