samples: ftrace: Include the nospec-branch.h only for x86
When other architectures without the nospec functionality write their
direct-call functions of samples/ftrace/*.c, the including of
asm/nospec-branch.h must be taken care to fix the no header file found
error in building process.
This commit (ee3e2469b346 "x86/ftrace: Make it call depth tracking aware")
file-globally includes asm/nospec-branch.h providing CALL_DEPTH_ACCOUNT
for only x86 direct-call functions.
It seems better to move the including to `#ifdef CONFIG_X86_64`.
