jvpp: provide more detailed exception logs (VPP-436)

Error descriptions provided in api_errno.h are never used,
only error tag/name and number make it to enum vnet_api_error_t
so new macro is introduced in jvpp_common.c to extract message
according to error number and passed to VppCallbackException
constuctor.
