devops: show package names instead of missing libs on Ubuntu 18.04 (#3013)

This patch starts putting package names to install on Ubuntu instead
of missing dependencies list.

The mapping of library to package name is obtained using the following
script: https://gist.github.com/aslushnikov/2766200430228c3700537292fccad064
