Improve var names in get_memory
realmem is the amount of actual (real) memory installed - the size of the RAM card - e.g. 256MB
physmem is the amount of memory available to FreeBSD after BIOS, video... has stolen some of realmem.
The variable names currently used are not very helpful for code readability. This standardises them. No functional change here.
