Title: prevent non-existent file from breaking play

fixes:
failed: [127.0.0.1] => {"failed": true, "item": "", "rc": 257}
msg: Destination /etc/sysconfig/iptables does not exist !

create=yes allows it to not fail on non-existent file, but because regex={{ httpd_port }} doesn't match anything, nothing is done (no file is created)
