Two OpenWrt updates

The OpenWrt
updates have been released. These updates contain some security fixes and
improved device support. It's noting that this is the last 19.07 update:

OpenWrt 19.07.10 is the final release of the 19.07 release branch,
this branch is now end of life and we will not fix problems on this
branch any more, not even severe security problems. We encourage
all users still using OpenWrt 19.07 to upgrade to OpenWrt 21.02 or
more recent OpenWrt versions.

Router distributions are easy to forget about; now might be a good time to
check any relevant systems and, if needed, doing an upgrade.
