Ignore trailing junk on .gz by default, to emulate gzip.

pigz would always issue a warning and return a non-zero error code
if the input gzip stream had non-gzip junk at the end. Now pigz
behaves like gzip, which ignores the junk, unless -v (--verbose) is
given, in which case there is a warning and a non-zero return code.
