[PATCH v7 04/13] arm: Use the common syscall table

["André Almeida" <andrealmeid@igalia.com>]

Remove some of the duplicated code by using the common syscall number
table.

Signed-off-by: André Almeida <andrealmeid@igalia.com>

Changes from v6:
- Added back syscalls from 403 to 423 to local table. arm32 can't use the
common table for those syscalls, because arm doesn't implements compat_
entry points for syscalls like pselect6, ppoll, etc., and OABI uses compat_
entry points when it's available, so this would cause a build error.
