Installer script automatically does a partial upgrade on Arch Linux.

[threeoh6000]

What is the issue?

Arch Linux heavily discourages the use of pacman -Sy due to the fact that this refreshes the package repositories and could cause newer libraries to be installed. This is a huge issue due to the fact that tailscale may update dependencies and break other applications depending on this automatically without any user intervention and could be huge source of headache for users of pacman-based distros.

Tailscale's installer should only install the package and should not be updating the repository information on the system nor upgrading any other packages.

At present, the Tailscale automatic installer does a partial upgrade and this should not happen ever.

Steps to reproduce

1. Install Tailscale using install.sh
