Newer versions of GNU Privacy Guard place some files in a
private-keys-v1.d subdirectory of ~/.gnupg so calling shred on them
needs extra care (shred has no recursive option). Instead of relying
on globbing, use find to filter to a list of files under that tree
so that shredding them will still work.

Current usage of gpg keys involves a single role that adds, signs,
and removes the key all in one. Some jobs may need the GPG key
installed normally onto the remote host, then left in place, and
later removed. This change facilitates that.
