tests: hardcode terminfo entry for the terminfo color test

For the terminfo color test, make sure that the terminfo entry used is one
of our own choosing, by delivering a special "hgterm" entry (a copy of
ncurses' xterm-color), compiling it, and specifically pointing curses to it
using the TERMINFO and TERM environment variables.  This means we can
ignore the variability in different terminal definitions on different
platforms.
