xfrm: Support crypto offload for outbound IPv4 UDP-encapsulated ESP packet

esp_xmit() is already able to handle UDP encapsulation through the call to
esp_output_head(). However, the ESP header and the outer IP header
are not correct and need to be corrected.

Test: Enabled both dir=in/out IPsec crypto offload, and verified IPv4
      UDP-encapsulated ESP packets on both wifi/cellular network
