tracing: Declare system call tracepoints with TRACE_EVENT_SYSCALL
In preparation for allowing system call tracepoints to handle page
faults, introduce TRACE_EVENT_SYSCALL to declare the sys_enter/sys_exit
tracepoints.
Move the common code between __DECLARE_TRACE and __DECLARE_TRACE_SYSCALL
into __DECLARE_TRACE_COMMON.
This change is not meant to alter the generated code, and only prepares
the following modifications.
