build: fix module symbol collection if build_dir is a symlink
If PKG_BUILD_DIR contains symlinks, the generated Module.symvers will contain the resolved paths, not the virtual path with the symlink name. This breaks the filter for the module's own symbols, so to fix this ensure we also grep for the resolved path.
