vcl/qa/cppunit/GraphicTest: Don't test for the exact size of the png file. HEADmaster

Building with zlib-ng instead of zlib leads to the following error in the
testsuite:

| [_RUN_____] testSwappingGraphic_PNG_WithGfxLink::TestBody
| ./vcl/qa/cppunit/GraphicTest.cxx:528:testSwappingGraphic_PNG_WithGfxLink::TestBody
| equality assertion failed
| - Expected: 319
| - Actual  : 318

The different implementation of deflate() leads to a different result.

Use an approximation of the expected size instead of the exact value.
