Use regex::match wrapper instead of regexec.

This patch eliminates all calls to regexec except that by regex::match
itself.

There are no behavioural changes.

	* src/abg-corpus-priv.h: Mechanically substitute use of
	regexec with regex::match wrapper.
	* src/abg-suppression-priv.h: Ditto.
	* src/abg-suppression.cc: Ditto.
