analyze_outcomes: ignore patterns apply to whole suite

This may come in handy when ignoring patterns in test_suite_cipher for
example which is split in several .data files where we'll want to ignore
the same patterns.

Currently none of the entries had a '.' in the test suite name, so this
doesn't change anything for existing entries.
