[test] Fix use of 'sort -b' in SimpleLoopUnswitch on NetBSD
Add '-k 1' to 'sort -b' calls in SimpleLoopUnswitch tests, as required
for sort implementation on NetBSD. The '-b' modifier is ineffective
if specified without any key. Per the manpage:
Note that the -b option has no effect unless key fields are specified.
