makefile: honor DESTDIR flag.

1. Fix config installation not exec permission is needed.

2. Makefile install all in DESTDIR.

make install DESTDIR=/tmp/dest/

Before:
$tree /tmp/dest/
/tmp/dest/
└── usr
    ├── bin
    │   └── kata-collect-data.sh
    └── share
        └── defaults
            └── kata-containers
                └── configuration.toml

5 directories, 2 files

Now:
$tree /tmp/dest/
/tmp/dest/
└── usr
    ├── local
    │   └── bin
    │       ├── kata-collect-data.sh
    │       └── kata-runtime
    └── share
        ├── bash-completion
        │   └── completions
        │       └── kata-runtime
        └── defaults
            └── kata-containers
                └── configuration.toml

Fixes: clearcontainers#401
