Missing dependency for Clang 7-10 on Ubuntu 22

[lczech]

Hi there,

when using setup-cpp in GitHub Actions with os: ubuntu-22.04 and compiler: llvm-7 to llvm-10, I get the following error when building my source:

/home/runner/llvm/bin/clang++: error while loading shared libraries: libtinfo.so.5: cannot open shared object file: No such file or directory

This is solved by adding this step to my workflow:

sudo apt-get install libtinfo5

I hence suggest that this dependency should be installed by setup-cpp for these compilers automaticlly.

Cheers and so long
