Apply upstream fix for building against libc++ 12
During an exp-run for llvm 12 (see bug 255570), it turned out that
www/firefox-esr does not build with clang 12.0.0 [1]:

This is caused by firefox doing a lot of complex and fragile juggling with
system headers, and was reported upstream as
<https://bugzilla.mozilla.org/show_bug.cgi?id=1694575>, then fixed via
<https://hg.mozilla.org/mozilla-central/rev/f875a4ffd653>.
Hopefully the next esr drop will have this fix included, but for now I propose
the attached patch.
