s3:torture: add STR-MATCH-MSWILD test for is_in_path()

I want to assert at least some of the behavior as the
next commits will add a new abstraction that should
at least partly behave the same.

Note: case_[in]sensitive_idx is the index to the patterns
in the namelist, set to -1 on non-match, otherwise to
a value >= 0.
