David AndersonandDave Anderson 9f867ad2c5 .github/dependabot.yml: disable eager updates for Go. 
Given our development cycle, we'll instead do big-bang updates
after every release, to give time for all the updates to soak in
unstable.

This does _not_ disable dependabot security-critical PRs.

David AndersonandBrad Fitzpatrick 44d0c1ab06 ipn/ipnlocal: resolve exit node IP to ID at EditPrefs time. 
Without this, enabling an exit node immediately blackholes all traffic,
but doesn't correctly let it flow to the exit node until the next netmap
update.

David AndersonandDave Anderson db800ddeac cmd/derper: set Content-Security-Policy on DERPs. 
It's a basic "deny everything" policy, since DERP's HTTP
server is very uninteresting from a browser POV. But it
stops every security scanner under the sun from reporting
"dangerously configured" HTTP servers.

 		a320d70614 net/dns: fall back to copy+delete/truncate if moving to/from /etc/resolv.conf fails. 
In some containers, /etc/resolv.conf is a bind-mount from outside the container.
This prevents renaming to or from /etc/resolv.conf, because it's on a different
filesystem from linux's perspective. It also prevents removing /etc/resolv.conf,
because doing so would break the bind-mount.

If we find ourselves within this environment, fall back to using copy+delete when
renaming to /etc/resolv.conf, and copy+truncate when renaming from /etc/resolv.conf.
