Você está tentando instalar um pacote que foi criado para o RHEL7, em um servidor CentOS6. Alterne para o repositório do RHEL6 e você poderá instalar o pacote mssql-server sem problemas:
curl https://packages.microsoft.com/config/rhel/6/prod.repo > /etc/yum.repos.d/mssql-server.repo
sudo yum install -y mssql-server
EDITAR: Pelo que vejo, em packages.microsoft.com, o servidor mssql só está disponível para RHEL7 ( link ), onde pode ser instalado corretamente:
[root@d7200e620554 /]# cat /etc/redhat-release
CentOS Linux release 7.3.1611 (Core)
[root@d7200e620554 /]# curl https://packages.microsoft.com/config/rhel/7/mssql-server.repo > /etc/yum.repos.d/mssql-server.repo
