libsystemd-network: Speed up checksum computation using 64 bit integers

Improve the checksum computation by using 64 bit integers instead of the 16 bit
integers in the existing implementation. This change speeds up the computation
with approximately 78% both on 64 bit and 32 bit systems.

Please see RFC 1071 for details.
