Bridgedb shouldn't handout bridges from .ir and .sy

The public network in these countries is highly censored and the average non-gov-supported/non-suspicious internet connection a user can have is capped to 128kb/s (16KB/s) by authorities in ir.

I can't think of anything these bridges can offer to tor network and its users other than harm and unmasking attacks.

Hopefully, we'd come up with a plan to prevent malicious activity by these bridges in long-term, but for now, we should stop handing them out.
