selftests/powerpc: Use req_max_processed_len from sysfs NX capabilities

On PowerVM, the hypervisor defines the maximum buffer length for
each NX request and the kernel exported this value via sysfs.

This patch reads this value if the sysfs entry is available and
is used to limit the request length.
