core: Always use runtime for gpgconf changes

Browse Source

* src/gpgme.h.in (gpgme_conf_opt_change): Document this
behavior.

If a tool uses GPGME for changing configuration values it
needs a way to ensure that these changes take effect. Otherwise
users may change and see config values and do not understand
why they are not working.
