[DistroKit] [RESEND][PATCH v1 6/6] v7a_noneon: run: really constrain the forwarded SSH port to <= 64000

[Roland Hieber <rhi@pengutronix.de>]

From: Ahmad Fatoum <a.fatoum@pengutronix.de>

The variable expansion braces should have been arithmetic evaluation
parentheses, which had the effect that the PPID was always used as a
port number (which incidentally works fine for PPIDs < 65535).

This was fixed in configs/platform-v7a/run by commit
fb3e1645e6b5 ("v7a: run: really constrain the forwarded SSH port to <= 64000"),
so apply the same fix here.

Fixes: 5d2b3d23b2da ("platform-v7a_noneon: sama5: platform w/out NEON extension")
