Current TA function execution time feature only reports user mode
execution time and exclude any non-user mode execution time. But in
case of syscalls which are essentially function invocations from TA
into the kernel, we shouldn't exclude syscall execution time in order
to account for actual function execution time. That means we only
exclude time that is spent serving foreign interrupts.
So changes in this patch allows to incorporate syscall execution time
in the function graph output.
Fixes: f5df167c2ffb ("ftrace: Add function execution time support")
