community/rest: disable failing tests and rebuild

- Remove oauth and oauth-sync tests since they fail
- Remove libsoup-dev from depends_dev since it is found by pkgconfig
- Move gobject-introspection-dev to makedepends since it is not required
 by the -dev package
- With the 2 above we can remove the depends_dev variable and use only
 makedepends
- Fix policy violations found by apkbuild-lint
