Subject: [PATCH] Fix CppunitTest_vcl_svm_test for big endian

These crc values are the results of Bitmap::GetChecksum() calls, and for
headless Linux the formats of those bitmaps (ScanlineFormat::N24BitTcBgr |
ScanlineFormat::TopDown vs. ScanlineFormat::N24BitTcRgb |
ScanlineFormat::TopDown) depend on little vs. big endian (see the definition of
SVP_24BIT_FORMAT in vcl/inc/headless/CairoCommon.hxx), so these tests failed on
big endian Linux s390x.

So I updated the tests with whatever values I got reported on s390x, whether or
not those values are actually correct...
