Generate the GST_PLUGIN_PATH using the `plugins` variable in subprojects

To build the documentation, we are maintaining a 'standardise' `plugins`
variable accross all modules to list all plugins and generate
documentation for them.

This is also used to get the right plugin path when inspecting plugins
for the documentation.
