[Buildroot] [PATCH/next 5/7] package/flutter-gallery: add a configure step

[Adam Duskett]

To clarify the next patch, add a configure step to flutter-gallery.mk.
The `$(HOST_FLUTTER_SDK_BIN_FLUTTER) build bundle` is in the configure step
because it generates several files needed for the flutter_gen_snapshot tool
to generate the target .so file.
