8306281: function isWsl() returns false on WSL2

[Domest0s]

Currently isWsl() function is looking for "Microsoft" string in the kernel release string ($ uname -r).
That's not always true. Namely, on Ubuntu 22.04 - currently the newest Ubuntu LTS and default OS for WSL in Microsoft Store. In there $ uname -r command outputs "5.10.102.1-microsoft-standard-WSL2".
This makes isWsl() function to return false in such environments and breaks JDK builds on WSL.

To correct that I made the substring search case-insensitive.
