base/stat.jl: Mask UV_EINVAL error codes for jl_stat

This fixes #26685, where libuv
decided to throw `UV_EINVAL` on windows for invalid-filepaths such as
`foo??` or `http://google.com`, instead of returning `UV_ENOENT` as they
were previously [0].  This causes windows to throw errors on calls such
as `isfile("http://google.com")`, whereas other platforms simply return
`false`.  This change simply ignores `UV_EINVAL` alongside the other
"allowed failure" error codes.
