fix(cli): Map error kind to PermissionDenied when symlinking fails due to permissions (#25398)

Browse source 
Fixes https://github.com/denoland/deno/issues/25333.

We fall back to junctions if the error kind is `PermissionDenied` but
the std library actually sets the kind to `Uncategorized` if the symlink
fails due to insufficient privileges. This was causing the fallback to
not actually fall back in this case.
