cr-exec: add non-generated sys-exec-tbl for x86

Browse source 
Impact: search sys-exec-tbl-32.c for compatible tasks.

Rename task_in_compat_mode to arch_task_compatible and use it in
find_syscall for 64-bit to check compatible task's syscall nr.
It still will not execute syscall in 32-tasks, as we still do not
have 32-bit pie (arch_can_dump_task will return false for these tasks).

NOTE: be sure to `make mrproper` on criu directory before applying this
patch, as before `criu/arch/x86/sys-exec-tbl.c` was autogenerated,
it will make conflict if you try to apply this patch on dirty directory.
