Hob: Fix toolchain build

Originally we added -dev and -dbg postfixes to our selected packages as
toolchain packages. However, some package names are modified in recipes,
so we could not rely on its base name. The new approach is to detect if
a package is selected, then include those packages under the same recipe
endswith "-dev" and "-dbg".

This fixes [YOCTO #2185]
