Generate stable bindata output

fixes #30621

bindata generation produces spurious diffs when run with different go versions because gzip output is not stable between versions.

It also produces spurious diffs when invoked directly vs via make/go:generate.

This PR:
* adds data to bindata uncompressed (makes translation files human-readable, and the zip files were already compressed... for reference the file was 27.7 KB before, and 20.1 KB with this change)
* runs the generation from KUBE_ROOT, so it doesn't matter whether it is invoked directly or via go:generate
