Relax the version restriction of libdeflate. https://bugs.gentoo.org/944285 Any API/ABI-compatible versions would be ok for app-arch/libdeflate, but in such case the build script of libdeflate_sys should be patched to pick even if the system library is newer. https://github.com/adamkewley/libdeflater/pull/32#issuecomment-1971198374 Also, don't forget updating `DEPNED` and `RDEPEND` in sync, or libdeflater crate will fail to pick the system library and silently use the bundled version of libdeflate.
