[oe] [meta-networking] [PATCH] mctp: upgrade 2.5 -> 2.6

mctp version 2.6 released on 2026-07-21, bump srcrev to the v2.6 tag.

The new version of mctpd can run as an unprivileged user with
CAP_NET_BIND_SERVICE and CAP_NET_ADMIN added to the process' ambient
capabilities. Added this unpriviledged user to the recipe when systemd
is available.
