ftrace/x86: Fix trace event registration for syscalls without arguments
The refactoring of SYSCALL_DEFINE0() macros removed the ABI stubs and
simply defines __abi_sys_$NAME as alias of __do_sys_$NAME.
As a result kallsyms_lookup() returns "__do_sys_$NAME" which does not match
with the declared trace event name.
See also commit 1c758a2202a6 ("tracing/x86: Update syscall trace events to
handle new prefixed syscall func names").
Add __do_sys_ to the valid prefixes which are checked in
arch_syscall_match_sym_name().
Fixes: d2b5de495ee9 ("x86/entry: Refactor SYSCALL_DEFINE0 macros")
