[Buildroot] [git commit branch/next] nginx: fix nginx.old clean-up

[Thomas Petazzoni]

commit: http://git.buildroot.net/buildroot/commit/?id=f6d1d1518c192b4e33b736528a68d4d1f20b10e8
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/next

The bin path for nginx is configured for /usr/sbin, so deleting
the nginx.old back-up from /usr/bin never works.  Fix path, and
also use "$(RM)" instead of "-$(RM)", as "rm -f" never fails.
