sys/linux: move some ARM-specific descriptions to a separate file

This is done to solve a particular test failure running:

 $ tools/syz-env go test ./prog -run TestSpecialStructs

, which failed on PPC64, because prog/rand.go instanciated a call to
syz_kvm_setup_syzos_vm(), which requested too much memory (1024 pages)
from the allocator (PPC64 uses 64k pages, so the number of available pages
is lower).

On the other hand, factoring out syzos-related descriptions is probably
a nice thing to do anyway.
