file: fix call to localtime_r()

Depending on the version of glibc, localtime_r() must
be preceded by a call to tzset() or it will ignore any
value of TZ in the environment.  This problem will only
be seen when building file-native on outdated hosts.

+Subject: [PATCH] print.c: initialize timezone data for localtime_r()
+
+The man page for localtime() points out that while it acts
+like tzset() has been called, localtime_r() might not.  We
+have a local version of localtime_r() that avoids this, but
+we do not compile it.
