xz: Add a new --filters-help option.
The --filters-help can be used to help create filter chains with the
--filters and --filtersX options. The message in --long-help is too
short to fully explain the syntax to construct complex filter chains.
In --robot mode, xz will only print the output from liblzma function
lzma_str_list_filters.
