cmd/link, plugin: use full plugin path for symbols
Plumb the import path of a plugin package through to the linker, and
use it as the prefix on the exported symbol names.
Before this we used the basename of the plugin file as the prefix,
which could conflict and result in multiple loaded plugins sharing
symbols that are distinct.

Fixes #17579
