ltp: Fix tescases with 64bit time_t using 32bit arches

This helps it compile on musl

Fixes

+Subject: [PATCH] syscalls: Check for time64 unsafe syscalls before using them
+
+musl is using 64bit time_t now on 32bit architectures and these syscalls
+no longer exist, therefore its better to check for them being available
+before using them
+
