fedora: multi-flavor support in kmod rpm spec

[gmmephisto]

What's new:

• added support for building kmod in isolated environment (in chroot using mock)
• added ability to build kmod for several kernel flavors (can be specified with -D 'kflavors default ...')

Fixes:

• fix incorrect override command in depmod config:

  • before:

    override * * extra
    override * * weak-updates
    

  • after:

    override vport-gre * extra/openvswitch
    override vport-gre * weak-updates/openvswitch
    override vport-lisp * extra/openvswitch
    override vport-lisp * weak-updates/openvswitch
    override openvswitch * extra/openvswitch
    override openvswitch * weak-updates/openvswitch
    override vport-geneve * extra/openvswitch
    override vport-geneve * weak-updates/openvswitch
    override vport-vxlan * extra/openvswitch
    override vport-vxlan * weak-updates/openvswitch
    override vport-stt * extra/openvswitch
    override vport-stt * weak-updates/openvswitch
    

• fix mixed tabs and spaces in spec file

@leifmadsen would you like to try this out? I figured you might be interested in the mock support.

I got this error on my first try building this on Fedora:

line 29: Dependency tokens must begin with alpha-numeric, '_' or '/': BuildRequires: %kernel_module_package_buildreqs

What am I missing? My first google hit made it sound like this may be a SuSE thing perhaps? Where are you running this?
