dovecot: fix size of time_t for 64-bit cross.

configure_args hard coded the size of the time_t type, which means
64-bit cross compiled archs, such as aarch64, were using the wrong type.
For little-endian, it would just break 2038-proofness, but BE machines
could have bigger issues.

A comment and commented out code were added to prepare for musl's time64
update.
