System-wide remote gpg homedir is not respected by `ostree show ...`

[RomanValov]

On a vanilla fedora-iot image system-wide /etc/ostree/remotes.d configuration used to configure fedora-iot remote and gpg-homedir to be used (/etc/pki/rpm-gpg).

These gpg keys are considered by various ostree admin ... commands and by ostree pull command, but not by ostree show command:

[root@ostree ~]# ostree pull fedora-iot:fedora/stable/x86_64/iot

I'm facing the same issue on below environment for both pull and show commands.
