weston: Restore partial clients for i.MX 6 and 7

The clients configuration for fbdev was recently removed from
meta-freescale [1] because of the following error:

```
| Run-time dependency gbm found: NO (tried pkgconfig and cmake)
|
| clients/meson.build:134:4: ERROR: Problem encountered: weston-simple-dmabuf-egl requires gbm which was not found. If you rather not build this, drop "dmabuf-egl" from simple-clients option.
```

It was also removed for non-Wayland from OE-core [2] because of the
following error in the same client dmabuf-egl:

```
clients/meson.build:141:4: ERROR: Problem encountered: weston-simple-dmabuf-egl
requires option renderer-gl which is not enabled. If you rather not build this,
drop "dmabuf-egl" from simple-clients option.
```

Restore the working subset of clients.
