mkefidisk.sh: Improve logging

Add logging functions: error, warn, info, and success, using tput to add
color highlighting.

Use these routines throughout the script, replacing echo statements and
adding "|| error" in several places to eliminate silent failures. Add a
simple exit block which checks for issues encountered while running.
