cmds.projects.CmdBuild: Support --dep-flavours

CmdBuild caters for the needs of the targets all, clean and pkg-*. It
uses builtin dependency flavours matching those targets to resolve
build order. To make it more flexible in general and support more
targets, e.g. check and test, add a --dep-flavours option.
