Tests: Fix warnings from clang --Wassign-enum.
Explicitly casting the integer to lzma_check silences the warning. Since such an invalid value is needed in multiple tests, a constant INVALID_LZMA_CHECK_ID was added to tests.h. The use of 0x1000 for lzma_block.check wasn't optimal as if the underlying type is a char then 0x1000 will be truncated to 0. However, in these test cases the value is ignored, thus even with such truncation the test would have passed.
