When processing subunit streams we attempt to discover where the (s)testr commands are located. For some reason the output of our scripts that do this very occasionally emit a newline before the command path. When this happens we were using the blank line as the command path which fails as that empty command results in our command arguments being interpreted as the command path. Attempt to address this by trimming the stdout instead of taking the first line. This should remove the leading and trailing newlines and give us only the command itself.
