tools: libdeflate: bump to 1.22

Bump to the latest 1.22 version which allows dropping our only patch.

Changelog:
Version 1.22
* The CMake-based build system now implements a workaround for gcc being paired
  with a too-old binutils version.  This can prevent build errors.

Version 1.21
* Fixed build error on x86 with gcc 8.1 and gcc 8.2.

* Fixed build error on x86 when gcc 11 is paired with a binutils version that
  doesn't support AVX-VNNI, e.g. as it is on RHEL 9.

* Fixed build error on arm64 with gcc 6.

* Fixed build error on arm64 with gcc 13.1 and later with some -mcpu options.

* Enabled detection of dotprod support in Windows ARM64 builds.
