Update Debian control file to remove unencrypted git protocol

[krvaibhaw]

Description

GitHub recently updated Git protocol security, and the usage of the unencrypted git protocol has been retired permanently on March 15th. But, the Debian control file deb.control still used git protocol for Vcs-Git. Hence, may lead to bunch of unauthenticated git protocol errors.

Proposed Solution

Use https protocol in place of unencrypted git protocol

git://github.com/ethereum/go-ethereum.git should be changed to
https://github.com/ethereum/go-ethereum.git
