Add explicit version dependency on xz-libs since the version number built
against is embedded into the module and can cause failures in users of this
module if they compare build-time and run-time versions of liblzma.
- New upstream release 2.031
- Changed to build with XZ 5.0.0
- Dropped symbolic constants provided by subblock.h (CPAN RT#62461)
- Drop xz 5.x patch, no longer needed
- The xz API changed slightly for the 5.0.0 release, removing support
for sub-block filters and bumping the library soname to liblzma.so.5.
This update patches out the now-missing constants so that the
package can be built with the new library.
The issue has been raised upstream as CPAN RT#62461
