Get rid of msys2 checks on build.yml

Why to do this:

- It fails with no reason and hides real compilation problems
- MSYS2 was not supported until lately, and is a marginal platform. It makes no sense do such an exhaustive check for a platform seldom used.
- Takes a long time.
- Cygwin and msys2 are greately superseeded by wsl.
- Visual studio is more tested and preferred, Community edition is free.

So, I delete entirely all MSYS2 checks. If compelling reasons to incorporate those are found, version control of git is our friend.
