firefox: Fix evaluation with newer nixpkgs

A recent nixpkgs change[1] added an explicit requireSigning attribute,
which in turn sets MOZ_REQUIRE_SIGNING to a zero-width string.

The change also changed the check in the Firefox wrapper to check
whether the browser derivation exposes a requireSigning attribute, which
it doesn't.

Since I'm busy with other things and just want my machine configuration
to evaluate, I quickly worked around this by re-adding the
requireSigning (and allowAddonSideload for that matter) to the
derivation attributes on our side.
