dev-lang/nim: build and install 'nimble' and other tools, bug #631512

Defauld './koch install' installs only 'nim' binary as it uses
'compiler.ini' configurations. But there is no easy way to install
other tools.

After this change ebuild builds and installs tools explicitly
to expose them to users.
