[PATCH liburing v1 6/9] arch: syscall: Remove `__INTERNAL__LIBURING_SYSCALL_H` checks

[Ammar Faizi <ammarfaizi2@gnuweeb.org>]

From: Ammar Faizi <ammarfaizi2@gnuweeb.org>

We will include the syscall.h from another place as well. This check
was added by me when refactoring the x86 syscall. For aarch64 we will
include this header from lib.h but we are restricted by this check.

Just remove it for all archs. User shouldn't touch this code directly
anyway.
