Enable critical logging before panics

[failfmi]

Currently, whenever the runtime panics with an actual written error (e.g. parent hash should be valid), there is only error returned, without actual critical logging:

running runtime function: Failed to call the runtime function exported function

The following log must appear:

CRITICAL target=runtime message=panicked at 'parent hash should be valid', -build error line- ext_logging_log_version_1 pkg=runtime module=go-wasmer

and afterwards

running runtime function: Failed to call the runtime function exported function.
