CreepJS uses the presence of a handful of macOS-version-specific fonts to
estimate the OS version. The spoofed macOS font set omitted these
discriminator fonts, so spoofed Mac contexts reported a font profile that
didn't match any real macOS version — an internal inconsistency. Add the
discriminator fonts to the macOS mapping so the spoofed set lines up with
a real macOS release.
