New v63003/gtm8889 subtest (tests GTM-8889 in V63003)

Tests the following release note:

The ZHELP command does not report errors after the user presses a <CTRL-C>. Previously, when exiting after a <CTRLC>, the utility reported an UNDEF error and left a GT.M help dump file for analysis. (GTM-8889)
