We have "Conflicts: kernel < 3.10.0-514" on rpm package to make sure
the environment is running newer kernel.
However, user may use non-standard kernel which has different package name,
like kernel-ml or kernel-uek.
On such environment Conflicts tag does not works correctly.
Even the system running with newer kernel, rpm only checks "kernel" package
version number.
To avoid such issue, we need to drop Conflicts tag.
