fix(concatjs): tsc-wrapped compilation workers are subject to linker race-conditions

[devversion]

The linker is prone to race conditions in persistent workers, or non-sandbox environments (like
windows). This is because the linker for all workers will operate on a shared execroot directory
and the same node_modules directory is modified all the time / potentially conflicting with other
linker processes from other concurrently-running workers.

We rely on the patched module resolution anyway, but just need to disable the unused linker to avoid
issues like the following:
