repo-add: don't break if delta package sources contain epoch

Browse source 
Our sed parser for xdelta3 headers will greedily match on ":" which
coincidentally is also the character we use to define a version with an
epoch.

While we are at it, simply use sed for the whole pipeline, rather than
using both grep and sed.

Fixes FS#61195
