net-analyzer/netwatch: EAPI7->8, drop dead urls, lto+clang16 fixes

Also remove IUSE=doc and install the single pre-gen html
file uncoditionally.

May be an easy fix wrt #861203 but haven't looked, passing
-fno-strict-aliasing just as better than nothing (did need
a patch for lto mismatch either way).
