build: fix docker build on arm/v6

Unexpectedly the team which runs the Go docker images have removed the
arm/v6 image which means that the rclone docker images no longer
build.

One of the recommended fixes is what we've done here - switch to the
alpine builder. This has the advantage that it actually builds arm/v6
architecture unlike the previous builder which build arm/v5.

## Making a manual build of docker
The rclone docker image should autobuild on via GitHub actions. If it doesn't
or needs to be updated then rebuild like this.
See: https://github.com/ilteoood/docker_buildx/issues/19
See: https://github.com/ilteoood/docker_buildx/blob/master/scripts/install_buildx.sh
To do a basic build of rclone's docker image to debug builds locally:
```
docker buildx build --load -t rclone/rclone:testing --progress=plain .
docker run --rm rclone/rclone:testing version
```
To test the multipatform build
```
docker buildx build -t rclone/rclone:testing --progress=plain --platform linux/amd64,linux/386,linux/arm64,linux/arm/v7,linux/arm/v6 .
```
To make a full build then set the tags correctly and add `--push`
```
git co v1.54.1
docker pull golang
export DOCKER_CLI_EXPERIMENTAL=enabled
docker buildx create --name actions_builder --use
docker run --rm --privileged docker/binfmt:820fdd95a9972a5308930a2bdfb8573dd4447ad3
docker run --rm --privileged multiarch/qemu-user-static --reset -p yes
SUPPORTED_PLATFORMS=$(docker buildx inspect --bootstrap | grep 'Platforms:*.*' | cut -d : -f2,3)
echo "Supported platforms: $SUPPORTED_PLATFORMS"
docker buildx build --platform linux/amd64,linux/386,linux/arm64,linux/arm/v7 -t rclone/rclone:1.54.1 -t rclone/rclone:1.54 -t rclone/rclone:1 -t rclone/rclone:latest --push .
docker buildx stop actions_builder
```
### Old build for linux/amd64 only
```
docker pull golang
docker build --rm --ulimit memlock=67108864 -t rclone/rclone:1.52.0 -t rclone/rclone:1.52 -t rclone/rclone:1 -t rclone/rclone:latest .
docker push rclone/rclone:1.52.0
docker push rclone/rclone:1.52
docker push rclone/rclone:1
docker push rclone/rclone:latest
