Move code to disable ASR to nat/

This patch moves the shared code present on
gdb/linux-nat.c:linux_nat_create_inferior and
gdb/gdbserver/linux-low.c:linux_create_inferior to
nat/linux-personality.c.  This code is responsible for disabling
address space randomization based on user setting, and using
<sys/personality.h> to do that.  I decided to put the prototype of the
maybe_disable_address_space_randomization on nat/linux-osdata.h
because it seemed the best place to put it.

I regression-tested this patch on Fedora 20 x86_64, and found no
regressions.
