buildlet: include details in GCEError.Error

Some of our logging in the coordinator includes pointers and repetition,
like so:

2022/09/27 19:16:27 failed with errors: [0xc02b50e120]
2022/09/27 19:16:27 Failed to create VM: "failed with errors: [0xc02b50e120]". Retrying after 1 second (attempt: 2).

The GCE error types only have MarshalJSON methods, so use that to show
more information. (This builds on the previous attempt in CL 428114.)
Remove the duplicate log, since the caller can log or otherwise handle
the error.

For golang/go#48857.
