scripts/ipkg-build: fix deprecated GZIP environment variable warning

According to gzip 1.7 release note:

The GZIP environment variable is now obsolescent; gzip now warns if
it is used, and rejects attempts to use dangerous options or operands.
You can use an alias or script instead.

Fix this warning by using pipe instead
