perf trace beauty: Simplify syscall return formatting 

Removing syscall_fmt::err_msg and instead always formatting negative
returns as errno values.

With this we can remove a lot of entries that have no special handling
besides the ones we can do by looking at the tracefs format files, i.e.
the types for the fields (e.g. pid_t), well known names (e.g. fd).
