Build system: Use GZIP_ENV instead of GZIP
Older versions of gzip assume the GZIP environment variable contains
flags[1]. Building netsniff-ng on a system with such a version of gzip
will yield the following error:
INST netsniff-ng/netsniff-ng
gzip -9 -c netsniff-ng.8 > netsniff-ng/netsniff-ng.8.gz
gzip: gzip: No such file or directory
A practical alternative to redefining GZIP in the Makefile seems to be
to use the GZIP_ENV make variable[2] instead.
[1] The GZIP environment variable was deprecated in gzip version 1.7.
See https://www.gnu.org/software/gzip/manual/html_node/Environment.html
and https://git.savannah.gnu.org/cgit/gzip.git/tree/NEWS for more
information.
