tails-unblock-network calls undefined log function
If the blacklist couldn’t be removed, it tries to call
doesn’t exist in POSIX shell. Of course there are very little chances
that this happens given we
rm -f it just before, so I wonder if it’s
worth making this script any more complex by sourcing the relevant
library file — perhaps we could just drop the check.
