    include: use libdeflate's gzip to decompress
    
    libdeflate decompresses much faster than gzip.
    
    Example:
    
    ~/d/openwrt> time gzip -dc dl/cmake-3.25.1.tar.gz > /dev/null

       sys time   32.21 millis    0.25 millis   31.96 millis
    
    ~/d/openwrt> time libdeflate-gzip -dc dl/cmake-3.25.1.tar.gz > /dev/null
    
    ________________________________________________________
    Executed in  523.04 millis    fish           external
       usr time  415.48 millis    1.07 millis  414.41 millis
       sys time  107.74 millis    0.15 millis  107.59 millis
    
    ~/d/openwrt> time gzip -dc dl/tessdata-4.1.0.tar.gz > /dev/null
    
    ________________________________________________________
    Executed in    8.99 secs    fish           external
       usr time    8.90 secs  530.00 micros    8.90 secs
       sys time    0.07 secs   63.00 micros    0.07 secs
    
    ~/d/openwrt> time libdeflate-gzip -dc dl/tessdata-4.1.0.tar.gz > /dev/null
    
    ________________________________________________________
    Executed in    2.74 secs    fish           external
       usr time    2.38 secs  537.00 micros    2.38 secs
       sys time    0.35 secs   66.00 micros    0.35 secs
    
    Place libdeflate into tools-core as it is needed to decompress other
    archives.
