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 `DEPEND` and `RDEPEND` in sync, or libdeflater
crate will fail to pick the system library and silently use the bundled
version of libdeflate.

This patch should be applied from ${WORKDIR}.
