```
link/Plan9: fix UAF of symbol names

Long term, linker backends will need to manage their own string tables
for things like this because my mandate is: no long-lived pointers
allowed in any of the codepaths touched by incremental compilation, so
that we can serialize and deserialize trivially.

Short term, I solved this with a couple calls to Allocator.dupe,
incurring some harmless leaks.

```
