`kool self-update` insists on elevated permission when not necessary

[Magne Rasmussen]

Describe the bug

When kool is installed in a location writable by the current user, kool self-update should not require elevated privileges.

Kool version and environment

kool version 1.13.2
Ubuntu 21.04

To Reproduce

$ curl -fsSL https://kool.dev/install | BIN_PATH=$HOME/bin/kool bash
$ kool self-update
[error] Updating kool version
you need to use 'sudo' to perform this task
$

Expected behavior

Since $HOME/bin/kool is writable by the current user, I would expect kool self-update to update itself.

Thanks for the ticket @magne !

We have added that because the usual installation under Linux does require it... we can improve it to really check the "writeability" of the current user on the binary, hence only showing the alert when really necessary.

PR ready #381 - should go into next release.
