Forbid `*` in the middle of the target host

[RReverser]

As @jsha pointed in #2981 (comment):

Agreed we want to remove internal * in target hosts, and remove it from support in the rewriter.

So decided to create an issue for 1) removal of support for this in rewriter code 2) having tests that check against such <target host /> occurences.

Looks like after #2981 was fixed by #3603, some new cases appeared:

cc @fuglede @jsha @Hainish @Bisaloo - can we attempt to fix these and, this time, add a linter rule to prevent adding similar rules in future?

I guess this will protect our extension from wildcard-in-the-middle attacks. 😄
