[PATCH 05/18] binman: Workaround lz4 cli padding in test cases

[Jiaxun Yang]

Newer lz4 util is not happy with any padding at end of file,
it would abort with error message like:

Stream followed by undecodable data at position 43.

Workaround by skipping testCompUtilPadding test case and manually
strip padding in testCompressSectionSize test case.
