libpng: avoid dangling link in libpng package

As for libpng recipe, the libpng.pc is a symbol link to libpng12.pc, if packaging them into two different packages, we will get a dangling link for libpng.pc, and when calculating rpm dependency with that file, we will get nothing.

Only keep one version of dev package to fix the issue.
