perf beauty open: Detach the syscall_arg agnostic bits from the flags formatter
We may want to use this in other contexts, like when formatting the
return of fcntl(fd, F_GETFL).
Make it have the following signature, so that we can set the formatter
for the return argument while processing the arguments of a syscall, as
fcntl, for instance, may return fds, flags, etc, so need different
return value formatters:
size_t formatter(unsigned long value, char *bf, size_t size);
This gets so detached from 'perf trace' internals that we may well get
all these and move to a tools/lib/syscall_beauty/ library at some point
and use it in other tools/ living utilities.
