Avoid sigpipe by looking at last IPAddress

The docker command to inspect returns 2 "IPAdress:" items.
Both are the same, just different sections of the docker
output command. To avoid getting a SIGPIPE from the grep
command, use the tail command line tool to just grab the
last IPAddress from the grep command.

Resolves openbmc/openbmc-build-scripts#16
