Update the script for test 1013 and 1014 to require:
- case-sensitive match for the curl feature list.
(Continue to allow case-difference for protocols. They've always been
in uppercase within curl config.)
- matching order for the protocol list.
(Continue to allow any order for features. autotools builds on
platforms without `sort -f` need it. E.g. Old Linux CI)
Also:
- fix casing of the `gsasl` feature in `configure`, to match `curl -V`
and cmake.
- delete obsolete comment.
Closes#14706
