libcompose is failing while building from other directories

[surajnarwade]

I have following two types of docker-compose files,

$ cat compose-test/build.yml 
version: "2"
services:
    foo:
        build: "./build"
        command: "sleep 3600"

$ cat compose-test/context.yml 
version: "2"
services:
    foo:
        build:
            context: "./build"
        command: "sleep 3600"

and I am getting following output:

$ libcompose -f compose-test/build.yml build
