Make the protocol/dumprestore.h header match restore's idea of the dump

header for the case where sizeof(time_t) != sizeof(int).  dumprestore.h
was embedding time_t when it should have been embedding int32_t.

Use time_to_time32() and time32_to_time() to convert between the
protocoll/file-format time and time_t.
