Zig Version

0.10.0-dev.3685+dae7aeb33

Zig Language Server Version

38210d3

Steps to Reproduce

Start zls in a project. If the zls binary is installed in a read-only directory, such as /usr/bin this will crash with a permission denied error.

Expected Behavior

zls doesn't try to drop any files next to its executable, and instead uses some alternative path such as zig-cache or /tmp.

Actual Behavior

zls tries to create a build_runner.zig file next to its executable. This often fails, for example when zls is installed in /usr/bin (tries to create /usr/bin/build_runner.zig), and needlessly pollutes the filesystem.

This was introduced in 38210d3e9183a77dfe10e0d0f4a79d2999ce3cf7.

Once we agree on a solution, I'd very much like to implement it. Cheers!
