Hook the pair enter/exit when using augmented_{filename,sockaddr,etc}_syscall(), this way we'll be able to see what entries are in the ELF sections generated from augmented_syscalls.c and filter them out from the main raw_syscalls:* tracepoints used by 'perf trace'.

As we'll also hook into the syscalls:sys_exit_SYSCALL for which there are enter hooks. This way we'll be able to iterate the ELF file for the eBPF program, find the syscalls that have hooks and filter them out from the general raw_syscalls:sys_{enter,exit} tracepoint for not-yet-augmented (the ones with pointer arguments not yet being attached to the usual syscalls tracepoint payload) and non augmentable syscalls (syscalls without pointer arguments).

Reflecting the fact that it now augments more than syscalls:sys_enter_SYSCALL tracepoints that have filename strings as args. Also mention how the extra data is handled by the by now modified 'perf trace' beautifiers, that will use special "augmented" beautifiers when extra data is found after the expected syscall enter/exit tracepoints.
