[release] src/goInstallTools: remove dlv-dap from missing tools

We hoped to use missing analysis tools to prompt users to update
dlv-dap since we want users to be using master. This results in
the Missing Analysis Tools notification to be constantly displayed,
which is distracting. We should replace this with other update
logic to keep users getting updates.
