If password has expired, credential fill no longer returns early,
so later helpers can generate a fresh credential. This is backwards
compatible -- no change in behaviour with helpers that discard the
expiry attribute. The expiry logic is entirely in the git credential
layer; compatible helpers simply store and return the expiry
attribute verbatim.

Store new attribute in cache.
