[archiso] Introduce cowfile_size= bootparam
If not set, nothing is changed in current behaviour. Since dm-snapshot allows to use as "COW" a file with any size, without caring about the the size of "origin", we can avoid creating a "COW" file of the same size as the "origin". This is really useful, when using as cow_device= a filesystem that is VFAT where sparse files are not supported, so if root-image.fs is 1000M, passing cowfile_size=25% will create a root-image.cow of 250M instead of 1000M.
