recreate_feed: fix 3rd party dependency error on the fly

3rd party packages still seem to have incorrect dependency
specifiers (e.g >2.6  instead of >=2.6, of <1.0 instead of <=1.0).
As we recreate the Packages file anyway at least fix it in there
so enigma does not think there are updates because of the warning
messages.
Remove unneeded install calls to create intermediate subdirectories
