Fix a build regression on Solaris

Fix a regression introduced in commit aeb26da4cb64c0e75c8d.

On an Illumos test machine, running the GCC compiler and the Solaris
link editor, the CMake build failed with the following error:

    ld: fatal: unrecognized option '--version-script=/.../libpng.vers'

The fix consists in avoiding the use of CMAKE_SHARED_LIBRARY_C_FLAGS
in version script checks on Solaris.

Also clean up the surrounding code, as follows:
 * Rename CMAKE_REQUIRED_FLAGS_SAVE to _SAVED_CMAKE_REQUIRED_FLAGS.
   (The name of an internal variable should not begin with "CMAKE_".)
 * Reformat the version script to optimize the vertical space.
