b2: reduce default --b2-upload-concurrency to 4 to reduce memory usage

In v1.63 memory usage in the b2 backend was limited to `--transfers` *
`--b2-chunk-size`

However in v1.64 this was raised to `--transfers` * `--b2-chunk-size`
* `--b2-upload-concurrency`.

The default value for this was accidently set quite high at 16 which
means by default rclone could use up to 6.4GB of memory!

The new default sets a more reasonable (but still high) max memory of 1.6GB.
