Subject: [PATCH 11/15] Fix stat64 st_[acm]time decoding for personalities with
 32-bit time_t

STRUCT_STAT.st_[acm]time are declared as unsigned int for some
personalities, while time_t is signed.

* printstat.h (DO_PRINTSTAT): If st_[acm]time have the same size as int,
explicitly cast them to int.
* tests/stat64-v.test: Test that negative time_t is decoded properly.
