Preserve the dumpable flag, which affects whether a core dump will be
generated, but also affects the ownership of the virtual files under
/proc/$pid after restoring a process.
Tested: Restored a process with a criu including this patch and looked
at /proc/$pid to confirm that the virtual files were no longer all owned
by root:root.
zdtm tests pass except for cow01 which seems to be broken.

Move prctl constants into own header. They are
arch independent.
The x86 specific ARCH_SET_GS should be fetched from <asm/prctl.h>
(instead of defining own ones).
