memdisk: additional cleanups
Additional stylistic cleanups. Rename "syscall" to "intcall" (we
can't call it __intcall without clashing with com32.h); use macros
instead of copying variables to different places with only the type
being different.
Also, only change the rm/pm jump instructions when actually relocating
the code.
