gfxstream: guest: remove unneeded dependencies in meson build

In the Fuchsia and meson builds, we can remove
dependencies on RenderControl and just replace
it with a stub.  That's because only Goldfish
needs RenderControl's "process pipe" logic to
initialize the VkDecoders.

The Fuchsia build may be migrated to Bazel over
GN, so that's why it's left unmodified.
