syscall.Select uses SYS_PSELECT6 on arm64 and mipx64x, however this syscall expects its 5th argument to be of type Timespec (with seconds and nanoseconds) instead of type Timeval (with seconds and microseconds) This leads to the timeout being too short by a factor of 1000. This CL fixes this by adjusting the timeout argument accordingly, similarly to how glibc does it for architectures where neither SYS_SELECT nor SYS__NEWSELECT are available.
