meta-tizen: gstreamer: don't require target wayland-scanner

Only native wayland-scanner will run when cross-compiling.
Requiring it for the target host won't work.

+Subject: [PATCH] configure: improve check for wayland-scanner binary
+
+The plugin doesn't need the wayland-scanner package to be built
+or run, it only needs the wayland-scanner program during compile time.
+
+When cross-compiling, build systems might not have the wayland-scanner
+package for the target system as it is a developer's tool, while it should
+still be possible to use wayland-scanner from the host system.
+
+This patch fixes it by not requiring the wayland-scanner package but
+just the binary itself.
+
+Note that the check is done outside of the PKG_CHECK_MODULES
+as it doesn't work inside of it.
