Split CBC dependencies in five

[Mizux]

on SVN Cbc is provided as a one tarball while on github it has been split in five packages:

https://github.com/coin-or/Cbc (depends on cgl)
https://github.com/coin-or/Cgl (depends on clp)
https://github.com/coin-or/Clp (depends on osi)
https://github.com/coin-or/Osi (depends on coinutils)
https://github.com/coin-or/CoinUtils

-> use this five package instead of the svn tarball, this will ease the build of or-tools package later (with distro package dependencies)
note: on repology you can found the later layout and very few Cbc package
e.g. coin-or-cbc

This will also fix #379
