cmake: Fix dependencies of newly-stubbed libraries

Some downstream projects may only link to e.g. the glslang::SPIRV
library and rely on transitive dependencies to pull in everything else.
To keep this working, the SPIRV and MachineIndependent library stubs are
now linked against the glslang library.
