[3/3] kernel32: GlobalMemoryStatusEx: always report at least 1 byte of virtual memory even if none is available

[Fabian Bieler]

This patch decreases the amount of physical memory reported by 1 byte.

Titan Quest refuses to start if TotalPageFile <= ullTotalPhys with the error 
message: "Virtual memory must be enabled to run Titan Quest."

This is a work-around for users unwilling to add swap space.

If this patch won't go into the master, please apply the previous two patches 
alone.
