package/wlroots: vulkan renderer depends on vulkan loader
Without the vulkan-loader package present, the configure step fails with the
following error message:
```
Run-time dependency vulkan found: NO (tried pkgconfig and system)
Message: Install "vulkan" or pass "-Dvulkan=disabled" to disable it.
```
The above error is due to the lack of the vulkan.pc file provided by the
vulkan-loader package. A search of autobuild failures containing
BR2_PACKAGE_WLROOTS=y and BR2_PACKAGE_MESA3D_VULKAN_DRIVER=y shows two build
failures. However, the failure reasons happened before wlroots could compile.
One for gerbera-1.10.0 and another for host-rust-1.64.0.
Add a dependency on the vulkan-loader package to resolve the above issue.
