[Piglit] [PATCH 2/2] cmake: Link test utils with "-ldl"

[Jussi Kukkonen]

Without this linking CXX executables (e.g. fbo-blit-stretch) fails
with gold linker:

| libpiglitutil_gl.so.0: error: undefined reference to 'dlsym'
| libpiglitutil_gl.so.0: error: undefined reference to 'dlerror'
| libpiglitutil_gl.so.0: error: undefined reference to 'dlopen'
