trace: [*-user] Add events to trace guest syscalls in syscall emulation mode
Adds two events to trace syscalls in syscall emulation mode (*-user):
* guest_user_syscall: Emitted before the syscall is emulated; contains
the syscall number and arguments.
* guest_user_syscall_ret: Emitted after the syscall is emulated;
contains the syscall number and return value.
