[interpreter] Make --ignition-filter script filtering explicit.

[interpreter] Make --ignition-filter script filtering explicit.

This makes it explicit when the --ignition-filter pattern should be
applied to the script name instead of the function name by using a
proper "s:{name}" pattern. It also hardcodes it to be a prefix match
instead of an exact match, because that is all we need for test262.
