liblzma: Reword lzma_str_list_filters() documentation.

This further improves the documentation from commit
f36ca7982f6bd5e9827219ed4f3c5a1fbf5d7bdf. The previous wording of
"supported options" was slightly misleading since the options that are
printed are the ones that are relevant for encoding/decoding. It is not
about which options can or must be specified.
