tests: fix spurious failure with non-ANSI terminals

* t/ax/tap-summary-aux.sh: When checking colored testsuite output,
be sure to export the TERM variable to the value "ansi"; otherwise
the automake testsuite driver will not display colored output, not
even if AM_COLOR_TESTS is exported to "always".  Failure revealed
by NixOS Hydra.
