ExcServerVariants test: make the mock test port dispositions reflect reality

ExcServerVariants test: make the mock test port dispositions reflect reality.

These port dispositions were naïvely taken from excUser.c and
mach_excUser.c, but the local and remote portions were not swapped as
they would be upon receipt in a server. This swaps them to match how
they’d be visible in a server, and uses the port disposition name
aliases expected to be used in servers: MACH_MSG_TYPE_PORT_* instead of
MACH_MSG_TYPE_{MAKE,COPY,MOVE}_*.
