SystemTest_Compare binary files with gdalinfo statistic

[Bang Pham Huu]

Due to in some tests, somehow the size (and some binary data) of test output and test oracle is different, especially jpeg2000 cases. So instead of comparing binary by binary, we can compare the gdalinfo (to check metadata) and statistic (to check values) are the same between output and oracle.

e.g:
