networking: write configuration in doInstall

Short story:

Ifcfg files are (still) copied from installer environment instead of
generating from ksdata[1].

Details:

Ifcfg files can be created during installation
- in dracut: based on boot options and kickstart
- in anaconda: missing default ifcfg files[2]
- in GUI using nm-c-e

Going through ksdata here (update ksdata in spoke.apply and write ifcfg
files from ksdata at the end of install - writeNetworkConf in doInstall [3])
- which is what we would generally do for other spokes - is not necessary,
and has some caveats:

We'd need to update ks network command to mirror all configuration doable
in ifcfg files with nm-c-e (plus wireless credentials stored in keys-<device>
files, routing stored in yet another network-scripts files) and keep
up with every update of nm-c-e options instead of letting nm-c-e just
write the configuration for us. Also NM can update ifcfg files on its
own after they are written - another opprotunity for missync.

[1] Beside ifcfg files we also copy /etc/sysconfig/network-scripts/keys-<device>
files. We might want to copy also routing files created in nm-c-e.

[2] this should go to dracut IMO.

[3] such would be the chain:

 -  dracut writes ifcfg files
 -  NM can update ifcfg when activating device
      (does anaconda need to update ksdata ?)
 -  anaconda can write missing default ifcfg files
 -  nm-c-e can modify ifcfg files (GUI configuration)
 -  anaconda stores ifcfg to ksdata (spoke.apply)
 -  anaconda dumps ksdata to ifcfg on /mnt/sysimage (doInstall)
 -  anaconda modifies configuration for storage devices,
    and to set ONBOOT default - currently this can't precede the previous
    step because we are changing NM_CONTROLLED which is not mirrored
    in ksdata, so we need also to sync ksdata in this step
