board_status: Allow for parsing longopts

This converts the argument parsing to allow us to add longopts
using GNU getopt(1).

Shortopts should be reserved for general parameters. Longopts can be
used to tweak specific behaviors. For example, we might wish to add
options to set SSH port, timeout, and authentication parameters
with "--ssh-port", "--ssh-timeout", "--ssh-identity", etc.
