control sshd-14 fails on Amazon Linux

[jonasduarte]

Amazon Linux set the parameter HostKey on the file “/etc/ssh/sshd_config” with the value "/etc/ssh/ssh_host_rsa_key", causing the control sshd-14 to fail.

To get it fixed I added a condition on the code block that set the valid_algorithms on the file ssh_crypto.rb, stating that when inspec.os[:name] returns ’amazon’, alg = alg53.
