qa: Use IP_PORTRANGE_HIGH on OpenBSD for dynamic port allocation

Browse Source 
The default ephemeral port range on OpenBSD (1024-49151) overlaps with
the test framework's static port range starting at TEST_RUNNER_PORT_MIN,
the same way FreeBSD's does (see #34346).

Extend `set_ephemeral_port_range()` to OpenBSD. The socket option and
its values are identical to FreeBSD's, so only the platform check
changes.

Using IP_PORTRANGE_HIGH avoids this overlap when binding to port 0 for dynamic
port allocation.
