feat: disregard -ec.X suffix when bumping k0s (#238)

* feat: disregard -ec.X suffix when bumping k0s

if we are shipping our own version of k0s we should only bump k0s
dependency when the prefix (whatever comes before -ec.X) has been
updated. we also need to clear the download url used.

* feat: using awk
