media-libs/vulkan-loader: Remove unnecessary Python dependency

There's an optional "VulkanLoader_generated_source" target that requires
Python 3, but it's not used during the build. Instead the generated
files are checked into git and thus are available in the tarball.

Noticed because of a patch in the chromiumos-overlay that moved
${PYTHON_DEPS} to BDEPEND (which would make sense if Python was actually
used during the build).
