package/rt-tests: add syscall-number for sched_(gs)etattr() for SH4

The dependency on kernel headers >= 3.14 was added by
b9fa6c00b1213fd038f2aed52057f22c7e18fd4b since
librttest requires __NR_sched_setattr and
__NR_sched_getattr syscalls (rt-sched).

But these syscalls have just been added to kernel 4.8 for SH4.

Fixes:
