flatpak_context_to_args() built the D-Bus name options from
flatpak_policy_to_string(). That function gives the values used in the
[Session Bus Policy] and [System Bus Policy] metadata groups. Two of
them, "none" and "see", are not command-line options. A context that
contained such a policy gave --none-name= and --system-none-name=.
flatpak-run(1) writes these arguments to the [Instance] extra-args of
/.flatpak-info. flatpak-portal gives them back to flatpak(1) when a
sandboxed app calls flatpak-spawn(1). flatpak(1) then rejected the whole
command line with "Unknown option --none-name=...", so --no-talk-name
and --system-no-talk-name broke flatpak-spawn(1).
Map each policy to the option that sets it: --no-talk-name for
FLATPAK_POLICY_NONE, --talk-name for FLATPAK_POLICY_TALK, and --own-name
for FLATPAK_POLICY_OWN. FLATPAK_POLICY_SEE has no command-line option,
so emit nothing for it. It cannot occur here: the only caller serializes
a context that comes from the command line.
