networkd vxlan: Add support for enabling UDP checksums
Add UDPCheckSum option to enable transmitting UDP checksums when doing
VXLAN/IPv4. Add UDP6ZeroChecksumRx, and UDP6ZeroChecksumTx
options to enable sending zero checksums and receiving zero
checksums in VXLAN/IPv6
[tomegun: rebase manpage due to whitespace changes]
