When set -f option, no set -f option automatically

[tzmfreedom]

Zend\Mail\Transport\SendMail always append envelope-from parameter.
But I want to set any envelope-from.
In this PR, only when not set option -f, set -f option automatically.
This means if I set -ffoo@example.com or -bs -ffoo@example.com, Zend\Mail\Transport\Sendmail doesn't set -f option.

without getting deeper to the actual changes, have some thoughts:

1. seems weird to have a negative parameter. how about set positive parameter which is b default true, and can be set as false.
2. maybe have a specific option (envelope related) rather generic "no override" as behavior could be different if want/want not to override some other parameter.

Thank you for you reply and advice !

I rethink, revise my code and changed this PR goal.

On this PR, only when not set option -f, set -f option automatically.
This means if I set -ffoo@example.com or -bs -ffoo@example.com, Transport\Sendmail doesn't set -f option.
So there is no negative parameter, no additional method.

you should update PR title as well. and the body is a bit hard to read as well.
