cm: Add a wrapper script for Curl which acts like wget
* Lots of stuff in the wild actually uses wget, and Toybox doesn't provide it. We already have Curl which does the same thing just with some different arguments. This wrapper script can handle it. Change-Id: Ic02da709fcd29808b96fabcd1ac4ddd9465f635f
