FreeBSD: Fix privilege escalation prompts not showing up (#1349)

Browse Source 
The behaviour of `wc -l` is different on FreeBSD, in which the stdout
result is padded by spaces in the beginning, which causes that the
result[0] is not actually the value we care about. This patch adds
a translate removing all whitespace from the output.
