testsuite: Remove reqlib modifier

The reqlib modifer was supposed to indicate that a test needed a certain
library in order to work. If the library happened to be installed then
the test would run as normal.

However, CI has never run these tests as the packages have not been
installed and we don't want out tests to depend on things which might
get externally broken by updating the compiler.

The new strategy is to run these tests in head.hackage, where the tests
have been cabalised as well as possible. Some tests couldn't be
transferred into the normal style testsuite but it's better than never
running any of the reqlib tests. https://gitlab.haskell.org/ghc/head.hackage/-/merge_requests/169

A few submodules also had reqlib tests and have been updated to remove
it.

Closes #16264 #20032 #17764 #16561
