realtek: Migrate to libdeflate
Libdeflate is a more advanced gzip compressor, which allows for faster
decompression, higher compression speed (factor 3-4), while being fully
gzip compatible.
Some comparison
gzip | libdeflate-gzip | delta | image [openwrt-realtek-rtl839x-*]
--------+-----------------+--------+-----------------------------------------------
6589174 | 6298794 | 290380 | d-link_dgs-1210-52-initramfs-kernel.bin
6291632 | 6029488 | 262144 | d-link_dgs-1210-52-squashfs-factory_image1.bin

6292264 | 6030122 | 262142 | zyxel_gs1900-48-squashfs-sysupgrade.bin
and changing lzma to (libdeflate-)gzip on existing rtl930x target:
