[Buildroot] [PATCH 1/2] yad: fix libgtk2 related dependency error

[Ricardo Martincoski]

When yad is built using gtk3 backend, gtk3-x11 needs to be selected too
or following error will occur
*** libgtk2 is in the dependency chain of yad ...

NOTICE: This fix requires the user to re-run Kconfig to update the
config file

The dependency now is enforced by Kconfig, so there is no more need to
test explicitly for gtk3-x11 at build time.

Another solution would be to explicitly test for (gtk3 and gtk3-x11) or
gtk2 at build time and generate a comprehensive error message when the
requirement is not meet. But the builds would still break.

Fixes:
