issue in ms-update-phishing for v5.0.7-1

[M A Young]

When running /etc/cron.daily/mailscanner if curl is failing for some 
reason the output is

/usr/sbin/ms-update-phishing: line 141: CURLORWGET: command not found
/usr/sbin/ms-update-phishing: line 245: CURLORWGET: command not found

These lines both include
CURLORWGET = 'wget'
which means CURLORWGET is seen as a command. It should be
CURLORWGET='wget'
so CURLORWGET is seen as a variable.
