compress/gzip: fix Reader to properly check FHCRC
RFC 1952, section 3.2.3 says:
>>>
If FHCRC is set, a CRC16 for the gzip header is present,
immediately before the compressed data. The CRC16 consists of the two
least significant bytes of the CRC32 for all bytes of the
gzip header up to and not including the CRC16.
<<<
Thus, instead of computing the CRC only over the first 10 bytes
of the header, we compute it over the whole header (minus CRC16).
Fixes #15070
