executor: fix endianness problem in internet checksum

csum_inet_update does not handle odd number of bytes
on big-endian architectures correctly. When calculating
the checksum of odd number of bytes, the last byte must be
interpreted as LSB on little-endian architectures and
as MSB on big-endian ones in a 16-bit half-word.

Futhermore, the checksum tests assume that the underlying architecture
is always little-endian. When a little-endian machine stores
a calculated checksum into memory, then the checksum's bytes
are automatically swapped. But this is NOT true on a big-endian
architecture.
