Currently sve-probe-vls does not verify that the vector lengths reported
by the prctl() interface are actually what is reported by the architecture,
use the rdvl_sve() helper to validate this.

The newline is expected to come from the caller but got missed for this
test.

Add a test case that verifies that we can enumerate the SVE vector lengths
on systems where we detect SVE, and that those SVE vector lengths are
valid. This program was written by Dave Martin and adapted to kselftest by
me.
