Build a fedora kernel rpm

Rationale:

• I need a custom kernel (because sound won't work with vanilla)
• I want to use Fedora Atomic Host
• The only way to override the kernel with Fedora Atomic Host is to install a kernel package using ostree-rpm
• I have a metered network connection and want to avoid downloading the kernel sources too many times
• The powerful machine that can build the kernel is nor running Fedora or Red-hat based system with rpmbuild available
