package/wpebackend-fdo: package needs wayland libegl

Now wpebackend-fdo depends only on HAS_LIBEGL but if libegl is not of
wayland type, build breaks due to different EGLNativeWindowType types
depending on backends(fb,x11,wl).

Modify:
'depend on BR2_PACKAGE_HAS_LIBEGL'
to:
'depend on BR2_PACKAGE_HAS_LIBEGL_WAYLAND'
in Config.in to avoid building if there is not a wayland egl backend.
Modify also comment in Config.in when package is not selectable
mentioning the need to have an OpenEGL-capable Wayland backend.

Fixes:
