kmodtool currently incorrectly identifies official
RHEL kernels, as opposed to custom kernels. This
can cause the openZFS kmod RPM build to break.
The issue can be reproduced by building a set of
mainline Linux RPMs, installing them, and then
attempting to build the openZFS kmod package
against them.
