Attachment: Bug 1841935 - Disable -fsanitize=function for C files.

Clang has recently added support for function UB sanitizing for C, but
it catches cases in e.g. NSS and SQLite that are IMHO a gray area rather
than a clear case of UB (https://reviews.llvm.org/D148827#4422709).

This still needs to be fixed, but I don't expect to come to it for a while.
