Small Cluster Shell Portability Fix

Hi,

I just tried the cluster shell in standalone mode on NetBSD, and it
works fine. One minor glitch: The top command doesn't work. I think
cluster-helper/get-childs contains some Linuxism; furthermore I added a
suitable top command for NetBSD to cluster-helper/top.in. The attached
patch (against Rev. 6342 in Robin's development branch) should fix both
issues.

Cheers,

Applied, thanks!
