configure: add SIZEOF_TIME_T to public_config.h

This has recently started being used by ext2fs.h.  Other users of the
ext2fs.h header would always get the 32-bit versions of the
__encode_extra_time, __decode_extra_sec, and __sb_set_tstamp; and the
64-bit version of __sb_get_tstamp, due to the SIZEOF_TIME_T macro
being undefined and treated as zero.
