FIX/cli/use.go: initial symlink to ~/.zvm/bin is never created

[guidoschmidt]

👋🏽 hello again 🙃

just tested the latest version (v0.6.5) on Windows and found a last small issue: if you didn't had the ~/.zvm/bin Symlink before, the current version early returns with an error:

Steps to reproduce:

F:\git\zig\zvm [master ↑1 +2 ~0 -0 !]> zvm version
zvm v0.6.5 windows/amd64



F:\git\zig\zvm [master ↑1 +2 ~0 -0 !]> ls ~\.zvm

    Directory: C:\Users\gs\.zvm

Simple fix

Just added a check if stat is nil. Everything else works like a charm 🙏🏼

Awesome, @guidoschmidt. Have I told you you're a king? Thank you for all the awesome PRs and contributions this week. Pretty sure you've directly or indirectly contributed to closing half the issues with ZVM on Windows.

@tristanisham thank you, I had a very strong motivation: I want to use zvm on my Windows machine 😇 glad I could help even without much Go experience
