From: Alistair Francis <alistair.francis@wdc.com>

Some 32-bit architectures (such are 32-bit RISC-V) only have a 64-bit
time_t and as such don't have the SYS_futex syscall. This patch will
allow us to use the SYS_futex_time64 syscall on those platforms.

This also converts the futex calls to be y2038 safe (when built for a
5.1+ kernel).

This is a revert of commit ba4026b09d83acf56c040b6933eac7916c27e728
"Revert "perf bench futex: Add support for 32-bit systems with 64-bit time_t"".

The original commit was reverted as including linux/time_types.h would
fail to compile on older kernels. This commit doesn't include
linux/time_types.h to avoid this issue.
