Patch

The change introduced in bug #256301 (review D30579), which prevents child make
processes from receiving an empty `FLAVOR` variable when `FLAVOR` should be
unset has the side effect of allowing any `FLAVOR` already in the parent make
process environment to propagate to the child.

The attached patch unsets `FLAVOR` before starting the child make.

Behavior before:
```
    $ make FLAVOR=zabbix54
    ...
    ===>  zabbix54-agent-5.4.1 FLAVOR is defined (to zabbix54) while this port
does not have FLAVORS.
    *** Error code 1
    Stop.
    make[1]: stopped in /usr/ports/net-mgmt/zabbix54-agent
    *** Error code 1
    Stop.
```

Expected behavior after:
```
    $ make FLAVOR=zabbix54
    ...
    ===> Fetching all distfiles required by zabbix54-agent-5.4.1 for building
    $ echo $?
    0
```
