Cherry Zhang a444458112 cmd/compile: make sure linkname'd symbol is non-package
When a variable symbol is both imported (possibly through
inlining) and linkname'd, make sure its LSym is marked as
non-package for symbol indexing in the object file, so it is
resolved by name and dedup'd with the original definition.

Fixes #42401.
