firefox: unveil pcscd socket to make smart cards work

Besides the now complete pcscd/munlock patch on ports@, the pcscd(8)
socket is all that is needed for smart cards to work out of the box with
/usr/local/lib/pkcs11/opensc-pkcs11.so (and probably other modules).

I didn't build a new package with this diff due to resource constraints,
but instead just tweaked /etc/firefox/unveil.main after tracing Firefox.

The ESR diff is untested but included for completeness as I'm under the
impression hat those pledge/unveil files should stay in sync.

If adding such paths is acceptable, I can test the chromiums next.

Feedback? Objection? OK?
