Fix outdated comment on __fallthrough__

Since commit 31dd071e927a ("Change .fallthrough to __fallthrough__")
this pseudo control statement is declared via underscores, not like a
proper control statement. That was done in order to avoid clashes with
ca65, and in order to allow nasm's --prelude to produce a .macro
replacement for it when using ca65.
