In Perl_sv_pos_u2b_flags and S_sv_pos_u2b_cached, return early for offset 0.

0 Unicode characters are always 0 octets long. Returning early ensures that
any offsets we calculate later will always be non-zero.
(cherry picked from commit 48f9cf718354a5326f9e9d40d02a063952160024,
as this is a prerequisite for 3e2d381)
