install without sudo

Fixes #23

[bHacklv]

Hi, this "fix" has broken our CI (after upgrading to v0.8, so we had to rollback to v0.7).

You should have parameterised sudo usage and allowed consumers to decide whether to use it or not.

Now with v0.8 I get this:

tar xzf - -C /usr/local/bin ko
tar: ko: Cannot open: Permission denied
tar: Exiting with failure status due to previous errors
Error: Process completed with exit code 2.

With v0.7 it was working fine

@bHacklv are you using vanilla github actions runners or something else like self hosted runners?

i can make a fix and make sudo an option to be used or not

@dprotaso Experiencing the same issue and can report we have our own self hosted runners

Private self-hosted, based on ghcr.io/actions/actions-runner.
I've tried with ubuntu-latest GH runner, and indeed, sudo is not required in that case.
