[PATCH 1/4] Remove deprecated dbkey support from doebuild/ebuild.sh

Remove the support for the dbkey logic that used to write metadata into
a file.  This logic has stopped being used and became deprecated
in 2013.  If any external tool is still using it, it's probably been
broken by changes in metadata itself since, and would definitely
be broken by the incoming change in metadata format.
