zip: set PWD consistently for commands in subdirectories

Some platforms (notably macOS) use symlinks for /tmp, so if we fail to
set PWD appropriately, any resulting errors may refer to the wrong
directory, making those errors more confusing.

This repository holds packages for writing tools that work directly with Go module mechanics. That is, it is for direct manipulation of Go modules themselves.

It is NOT about supporting general development tools that need to do things like load packages in module mode. That use case, where modules are incidental rather than the focus, should remain in x/tools, specifically x/tools/go/packages.

The specific case of loading packages should still be done by invoking the go command, which remains the single point of truth for package loading algorithms.
