Fix test cases for big-endian systems

A number of test cases were failing on big-endian systems simply due to
byte order assumptions in the tests themselves, and no underlying bug
in LLDB.

These two test cases:
  tools/lldb-server/lldbgdbserverutils.py
  python_api/process/TestProcessAPI.py
actually check for big-endian target byte order, but contain Python errors
in the corresponding code paths.

These test cases:
  functionalities/data-formatter/data-formatter-python-synth/TestDataFormatterPythonSynth.py
  functionalities/data-formatter/data-formatter-smart-array/TestDataFormatterSmartArray.py
  functionalities/data-formatter/synthcapping/TestSyntheticCapping.py
  lang/cpp/frame-var-anon-unions/TestFrameVariableAnonymousUnions.py
  python_api/sbdata/TestSBData.py  (first change)
could be fixed to check for big-endian target byte order and update the
expected result strings accordingly.  For the two synthetic tests, I've
also updated the source to make sure the fake_a value is always nonzero
on both big- and little-endian platforms.

These test case:
  python_api/sbdata/TestSBData.py  (second change)
  functionalities/memory/cache/TestMemoryCache.py
simply accessed memory with the wrong size, which wasn't noticed on LE
but fails on BE.
