liblzma: Allow nice_len 2 and 3 even if match finder requires 3 or 4.
That is, if the specified nice_len is smaller than the minimum
of the match finder, silently use the match finder's minimum value
instead of reporting an error. The old behavior is annoying to users
and it complicates xz options handling too.
