[Mesa-stable] [PATCH 2/2] glsl: return cloned signature, not the builtin one

[Ilia Mirkin]

The builtin data can get released with a glReleaseShaderCompiler call.
We're careful everywhere to clone everything that comes out of builtins
except here, where we accidentally return the signature belonging to the
builtin version, rather than the locally-cloned one.
