cycle: add --resident-mib

Pass the AdrenoX2 resident-map budget to the guest as the boot-arg
adreno_resident_mib=MIB (0 disables residency, at most 4096). An
ADRENO_RESIDENT_REPIN kext reads it; older kexts ignore the boot-arg.
Without the option the boot-args are unchanged.

The A16 desktop runs since b12v19r pass --resident-mib 1536. With this
option b12v20's argv reproduces its qualification's
boot_argument_addition exactly.
