[PATCH] linux: Fix fstatat with !XSTAT_IS_XSTAT64 and __TIMESIZE=64 (BZ #29730)

[Aurelien Jarno]

Commit 6e8a0aac2f883 ("time: Fix overflow itimer tests on 32-bit
systems") changed in_time_t_range to assume a 32-bit time_t. Therefore
stop calling it from __fstatat for systems with 64-bit time_t.

Resolves: BZ #29730
