gprofng: fix bug 29392 - Unexpected line format in summary file

gprofng/Changelog:
2022-07-22  Ruud van der Pas  <ruud.vanderpas@oracle.com>

	PR gprofng/29392
	* gp-display-html/gp-display-html.in: modified a regex, plus the
	code to handle the results; renamed a variable to improve the
	consistency in naming.
