Makefile: add '-n' to gzip invocations to improve reproducibility
Default invocation to gzip include timestamp in output file. This feature is
incompatible with BR2_REPRODUCIBLE. It is possible to disable it with '-n'.
The environment variable GZIP can hold a set of default options for gzip. So
instead to find all gzip invocation in build process, we just export 'GZIP=-n'.
Notice bzip2, lzma and xz are not impacted by this problem. On the other hand, lzop
does include timestamp and does not provide any way to disable it.
