tar: Support negative time values with pax

Pax extended headers may specify negative time values for files older
than the epoch.

Adjust the code to clear values to 0.0 more often and set ps to
INT64_MIN to have a proper error specifier, because the parser does
not allow anything below -INT64_MAX.

Fixes https://github.com/libarchive/libarchive/issues/2562
