[Piglit] [PATCHv2 2/2] cmake: Link test utils with "-ldl"

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'

Changes since v1:
* Use ${CMAKE_DL_LIBS} as Emil suggested

I'm adding the linker flag for all utils although I'm only seeing
the problem with libpiglitutil_gl.so -- I'm assuming it's because
the issue seems to only show with g++ and maybe the other
libs don't currently have tests that need g++?

Thanks, Jussi
