Remove attempt to handle all bs_match_string instructions

eb0b8da6e816 started to use a binary instead of a string in
bs_match_string instructions.

Remove a clause that attempts to handle the old form of
bs_match_string from old .S files. This is pointless, because an old
.S file is likely to contain a bs_context_to_binary instruction as
well. The bs_context_to_binary is no longer recognized by
`beam_validator`, so those old .S files will not work anyway.
