Install libyang in azure pipeline. (sonic-net#1124)

#### Why I did it
sonic-swss-common lib will add depency to libyang soon, so need install libyang lib to prevent build and UT break.

#### How I did it
Modify azure pipeline to install libyang in azure pipeline steps.

#### How to verify it
Pass all UT.

#### Which release branch to backport (provide reason below if selected)

#### Description for the changelog
Modify azure pipeline to install libyang in azure pipeline steps.

#### Link to config_db schema for YANG module changes
