Subject: [PATCH] test: fix cp.exec-any-shells test on windows with wsl

WSL bash files (from WindowsApps and System32) either cannot be
symlinked or don't work as expected from symlinks. This change detects
WSL bash and:
- Skips testing it if no WSL distro is installed.
- Skips symlink tests for all WSL bash executables.
