install.sh: install the SSH menu and its dependencies by default

fzf, tmux, jq, micro, nautilus, openssh-clients and friends are now part of
the default run, and ~/.ssh/sockets is always created. --full keeps the
remaining tools and the Flatpak apps. The menu's web action (Alt+W) falls
back to xdg-open when Chrome (Flatpak) is not installed.
