De-volatilize the internal implementation of `png_safe_execute`

`png_safe_execute` called `setjmp` in a context where the result was
undefined (an assignment statement). This corrects the code and removes
volatile statements that were introduced previously to quell warnings
from earlier versions of GCC.
