utils: fix removing unknown profiles that contain spaces

Browse Source 
aa-remove-unknown doesn't deal properly with profiles that contain
spaces in their names.

Using profile "MongoDB Compass" as an example, awk's sub returns the
number of matches - either 1 or 0 and replaces the actual string ($0)
with the substitution.  By accessing the return of sub with $, awk
would be accessing $1 which would return only "MongoDB".
Fix this by using $0 instead of $str.
