Subject: cmake: Turn modpost errors into warnings

Default changed some time between 6.1 and 6.6.
As we build the module for different kernel versions by fetching the
kernel sources and not compiling the whole kernel first, modpost always
complains aboit missing symbols after compilation. Ignore this as it's
expected to happen.
