don't disable repos while installing kernel (#84)
    
    * Update 02-install-packages.sh

    

    megi-kernel is a unique name and so now we don't need to disable repos to install the recommended software+megi-kernel. 

    So it can all be done at once.

    

    This was causing an error where pinephone-helpers could not find  iio-sensor-proxy from the main repo.
