Subject: [PATCH 11/12] Try switching to path_provider_linux

Now that plugin_tools are updated, try using path_provider again. Uses
path_provider_linux directly to avoid having an actual plugin dependency
for other platforms (e.g., an Android+Linux app shouldn't need to build
and ship the Android path_provider plugin just because the project uses
shared_preferences).
