Define SYS_futex on 32bit arches using 64-bit time_t

Newer 32bit arches like RISCV32 and ARC are using 64bit time_t from get go unlike other 32bit architecture therefore aliasing __NR_futex to __NR_futex_time64 helps avoid the below errors tst_checkpoint.c:99:17: error: use of undeclared identifier 'SYS_futex' Signed-off-by: Khem Raj <raj.khem@gmail.com> [ moved definitions to lapi/futex.h ] Signed-off-by: Petr Vorel <petr.vorel@gmail.com>
