stdlib: Allow lists with binaries in the Format argument
As a consequence of some refactoring (OTP-14983, option
'chars_limit'), the Format argument of io_lib:format() no longer
accepts binaries in lists in Erlang/OTP 21.0.
Note that if Format is not of type io:format(), control sequences in
Format are ignored. This can result in unpredictable behaviour if, for
example, the output of io_lib:format() is used as Format: if the
output happens to be a string(), then control sequences are
interpreted, otherwise not.
A check that Format is of type io:format() will likely be introduced
in Erlang/OTP 22.0. That will probably mean work for some users, but
considering how unpredictable io_lib:format() is, we should try to fix
that.
