[ygottlieb-peratonlabs-com]

Problem description

When installing the docker-compose package, the installed binary cannot be called as docker compose, rather it must be called as docker-compose

What steps will reproduce the bug?

1. Install docker-compose pkg install docker-compose
2. Run a compose command docker compose

The result is

docker: 'compose' is not a docker command.
See 'docker --help'

What is the expected behavior?

Docker should display the compose help:

Usage:  docker compose [OPTIONS] COMMAND

Fixing this requires two separate fixes:

1. docker-compose/build.sh must install docker-compose in @TERMUX_PREFIX@/libexec/docker/cli-plugins/.
2. Docker's cli/cli-plugins/manager/manager_unix.go must be patched to prepend @TERMUX_PREFIX@ to each element in the array.
