KEEP_BUILD_DIR is now honored

bugfix to honor KEEP_BUILD_DIR

[jhoekx]

Pavol, I don't get why adding the -n fixes a problem? With or without should be identical in both bash and coreutils test. Care to elaborate?

Okay, this is embarrassing, but I now cannot reproduce the problem we thought we fixed with -n in the morning: we've just seen temporary dirs polluting /tmp, with the NETFS backup, default KEEP_BUILD_DIR and no obvious error in log. I would swear, there was even You should also rm -Rf /tmp/rear.... message in log, but I cannot prove that anymore.

I close the request. I'll try to be more careful next time.
