core: Build _GO_PLUGINS_PATHS up, not down

I realized that the previous way `_GO_PLUGINS_PATHS` was getting built
would allow nested plugin paths to leak up into the environment of
plugins closer to the `_GO_PLUGINS_DIR` root. After considering how to
filter `_GO_PLUGINS_PATHS`, I realized the best solution was to build it
by walking up the directory tree whenever a plugin is executed.

Ironically, this is similar to another commit I'm working on in another
branch to find plugin files (specifically plugin modules, though the
mechanism is generic) in a similar fashion.
