Anna Henningsen 0b3936b49f zlib: Fix handling of gzip magic bytes mid-file ...

Only treat the gzip magic bytes, when encountered within the file
after reading a single block, as the start of a new member when
the previous member has ended.

Add test files that reliably reproduce #5852. The gzipped file
in test/fixtures/pseudo-multimember-gzip.gz contains the gzip
magic bytes exactly at the position that node encounters after having
read a single block, leading it to believe that a new data
member is starting.
