api, daemon: drop unnecessary dependency on github.com/go-openapi/run…

…time/flagext

Same case as for commit e63a1d4 ("api, daemon: drop unused
dependency on github.com/jessevdk/go-flags"), PR #10890.

The package is pulled in because the swagger server template uses it by
default.  However, we don't use any of the features of this package,
thus drop it.
