minor, extend dt_strfdt() to take a zdiff parameter, ...

Actually, this should be considered a hack, as the actual d/t data is decoupled
from this argument and completely inconsistent states are possible.
However, struct dt_dt_s as it stands has no space for an extra 11 bits
(minute-resolution, signed) to represent the tz difference as printable
by %Z.
