default.xml: Update source revision on meta-seco-rockchip

    This revision adds kprobes feature to linux-seco build and
    fixes the error "LTTng-modules requires CONFIG_KPROBES on
    kernels >= 5.7.0"

    When tools-profile are added to IMAGE_FEATURES, the lttng-modules
    build is activated and this requires the kprobes feature.
