Print all syscalls with the same details as strace

[pothos]

Currently we have some syscalls annotated to dereference buffer pointers. This could be automated with a script having a heuristic for the data in /sys/kernel/debug/tracing/events/syscalls/sys_enter_NAME/format where const and char * are useful hints. We will still need to fix some corner cases like dereferencing a read buffer at exit.
Besides dereferencing buffer pointers we have to display constants and structs in a nice way.
It would be good to see if we can use BTF and also if we can share code with strace.
