Fix ecp_check_pub() test cases

Negative x coordinate was tested with the value -1. It happens to be one
of the low order points both for Curve25519 and Curve448 and might be
rejected because of that and not because it is negative. Make sure that
x < 0 is the only plausible reason for the point to be rejected.
