ghcup: /usr/local/.ghcup: createDirectory: permission denied (Permission denied)

Why ghcup tries to create that directory.

This happens on CI with ghcup -v list. I see just

ghcup: /usr/local/.ghcup: createDirectory: permission denied (Permission denied)

without any other output, so -v flag doesn't help to figure out what ghcup tries to do, and why.

Figured out, there is GHCUP_INSTALL_BASE_PREFIX=/usr/local set on CI (for some reason, dont ask me).

Still I'd expected -v output to give me a hint of that.

We could do that. Seems like a simple PR
