shellspec adds spec/support/bin to the path, so we can put scripts that
should always be available here.
Also don't source sxmo_common.sh in the helper, if scripts don't do it
themselves we shouldn't do it for them in the tests.

The wait command will wait for all process known to the shell if no
arguments are passed, so in these cases looping does nothing.
