Add GitHub Actions CI, release, and Pages workflows, remove Travis CI

Add CI workflow (vet, test, cross-compile) that runs on pushes to
master and PRs. Add release workflow that builds binaries and attaches
them to GitHub Releases on tag push. Add Pages workflow that deploys
README.md to gh-pages on master push.

Remove .travis.yml (travis-ci.org is defunct). Update build.sh:
drop gox and dead secret ldflags, add arm64 targets. Update README
badge to GitHub Actions and modernize build instructions.

 ### Instructions for building yourself
-For newcomers the go build process can be a bit arcane, these steps can be followed to build `dbxcli` yourself.
 
-1. Make sure `git`, `go`, and `gox` are installed. 
-2. Create a Go folder. For example, `mkdir $HOME/go` or `mkdir $HOME/.go`. Navigate to it.
-3. `go get github.com/dropbox/dbxcli`. That's right, you don't manually clone it, this does it for you.
-4. `cd ~/go/src/github.com/dropbox/dbxcli` (adapt accordingly based on step 2).
+1. Make sure `git` and `go` are installed.
+2. Install the latest released version:
+   ```sh
+   $ go install github.com/dropbox/dbxcli@latest
+   ```
+3. Or build from source:
+   ```sh
+   $ git clone https://github.com/dropbox/dbxcli.git
+   $ cd dbxcli
+   $ go build .
+   ```

 ```sh
-$ export DROPBOX_PERSONAL_APP_KEY=your-app-key
+$ dbxcli login --app-key=your-app-key
 ```
 
-Finally we're ready to build. Run `go build`, and you'll see a `dbxcli` binary has been created in the current directory. Congrats, we're done!

 ## Usage
 
 `dbxcli` is largely self documenting. Run `dbxcli -h` for a list of supported commands:
