Fix clang-tidy header check

Apparently our exclusion of the linux headers covered up some issues in
our own headers, and was erroneously ignoring all headers, not just the
linux headers.

Apparently this now detects recursion quite a bit, so disable that check
for the moment, as well as the special member variables checks.  Also,
disable some cert checks that are duplicates of
bugprone-reserved-identifier, because of the aformentioned ignored linux
headers

All other changes are done automatically.
