You can't edef an input because it isn't expandable. You have to first read the contents of the file to a temporary variable and then pass that to setkeys.
Here's an expl3 implementation of setkeysFile. It's the same as the standard setkeys except that the second argument is a file that (should) contain a comma separated list of key-value pairs.
RequirePackagefilecontents
beginfilecontents*conf.tex
hello = world :D,
goodnews = everyone!,
endfilecontents*

usepackagexkeyval
