Reviewed by Michael Catanzaro.

When starting up a process programmatically on PlayStation an additional
argument is passed into `main` but the value in `argv` is actually null.
This causes a crash when `ENABLE(DEVELOPER_MODE)` is `ON`.

Just check the value's existence before sending it to `strcmp`.
