Add installed modules to initramfs with dracut

Fedora seems to be adding the stock tablet drivers to its initramfs. As
a result, newer tablets with VID:PID pairs already supported by the
stock modules won't work, if plugged before boot, since they will be
handled by the stock module.

Explicitly add our modules to Fedora initramfs, so those tablets work
even if plugged in before boot.

Fixes #238
