printf: allow 0 as a flag and allow multiple flags
The '%' character in a format specification may be followed by
one or more flags from the list "+- #0". BusyBox printf didn't
support the '0' flag or allow multiple flags to be provided.
As a result the formats '%0*d' and '%0 d' were considered to be
invalid.
The lack of support for '0' was pointed out by Andrew Snyder on the
musl mailing list:
