added a test for LZ4F_compressEnd()

which actively tries to make it write out of bound.
For this scenario to be possible,
it's necessary to set dstCapacity < LZ4F_compressBound()

When a compression operation fails,
the CCtx context is left in an undefined state,
therefore compression cannot resume.
As a consequence :
- round trip tests must be aborted, since there is nothing valid to decompress
- most users avoid this situation, by ensuring that dstCapacity >= LZ4F_compressBound()

For these reasons, this use case was poorly tested up to now.
