support/download: Add SFTP support
Add Secure File Transfer Program (SFTP) support using a simple wrapper.
SFTP is a common protocol used to transfer files securely between
enterprises, but it is not currently supported in Buildroot because all
of the packages are usually available via HTTP, git or some other
download method.
SFTP is similar to FTP but it preforms all operations over an encrypted
SSH transport using a specific protocol. This is unlike ftps, which is
traditional FTP over an SSL/TLS connection.

[Arnout:
- update documentation with sftp everywhere scp is mentioned;
- rename "verbose" variable to "quiet";
- print the sftp command, similar to wget and scp helpers.
