Change artifact matching to be more strict

The current artifact matching logic will cause any test target that uses
something like .*-tests.zip to be way too broad in what it causes to
build. Change the logic to look for the target name in the artifact
matching regex to make it so that only tests that look for a specific
target to match.

Test: atest build_test_suites_test
