[Buildroot] [git commit] package/protozero: disable tests

[Thomas Petazzoni]

commit: https://git.buildroot.net/buildroot/commit/?id=be4869f393561aa5c297b631efc62dfd5e1c3f3f
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Add a patch to disable tests through the standard BUILD_TESTING variable
which is already passed by cmake-package.

While at it, drop protobuf dependency which is only needed for tests

This will fix a build failure on toolchains without wchar, toolchains
for sh4 (ICE) or toolchains where gcc is affected by bug 64735.

Upstream thinks that this is unecessary but no additional feedback was
received on how we should handle those build failures

Fixes:
