libtraceevent: Fix backward compatibility with tep_print_arg_string

It appears that trace-cmd 2.9.6 referenced the tep_print_arg_string to
get to the offset, which was removed by libtraceevent commit 512d7be1
("libtraceevent: Add __rel_loc relative location attribute support").
Add the offset back to both tep_print_arg_string and to
tep_print_arg_bitmask (yeah, it adds a hole in the structure), for
backward compatibility.
