Subject: [PATCH] shared/compat: fix memory handling of
 nm_setting_vpn_get_*_keys

The compat implementations return a (transfer none) strv instead of a
(transfer container) one. This has caused double frees in nm-applet:
https://bugs.archlinux.org/task/56772

Don't copy the keys and don't free the container later.

[thaller@redhat.com: patch adjusted to avoid compiler warning]

Patch imported from NetworkManager commit 8ac8c01162235c2c198bfaf25fb7d1a57a595ce5.
