[tailscale] runtime/debug: embed Tailscale toolchain git rev

This is another take on #49 (which we stopped using?), and less
intrusive, and also always on.

This puts puts the the Tailscale Go toolchain's git rev in
the binary, accessible as a new "tailscale.toolchain.rev"
runtime/debug.BuildInfo Setting.

Caller code will have to access it guarded by the "tailscale_go" build
tag.

Updates #49

by default.

If a Go process starts up, finds /etc/resolv.conf empty, then the DHCP
client writes /etc/resolv.conf, the Go program would find itself
broken for up to 5 seconds.
