meta-ampere: bmcweb: set http-body-limit to 65

Ampere Mt.Jade platform has 64MB SPI-NOR but the default http-body-limit
is just 30. It makes firmware update via WebUI or Redfish is fail to
work when many features added.
This commit increases the http-body-limit value to 65 to avoid firmware
update failure.

Tested:
1. Add full Mt.Jade features and verify if firmware update works well
