The key folder is used by `opkg` and `usign` to store and retrieve trusted public keys. Using `opkg-key` outside a running device is unfeasible as the key folder is hard coded to `/etc/opkg/keys`. This commit adds a variable OPKG_KEYS which defaults to `/etc/opkg/keys` if unset, however allows set arbitrary key folder locations. Arbitrary key folder locations are useful to add signature verification to the ImageBuilders. Signed-off-by: Paul Spooren <mail@aparcar.org>
