GHA/windows: avoid curl.exe libtool wrapper

Avoid the `curl.exe` wrapper binary created by libtool, and run the real
`curl.exe` directly for tests and version information.

This solution was used in Azure jobs. I missed it when migrating jobs
to GHA.

Applies to tests run in the `mingw, AM x86_64 c-ares U` job, which has
seen unexplained flakiness.

Follow-up to e53523fef07894991c69d907a7c7794c7ada4ff4 #14859
