Now that we don't need to print the IP/ADDR for callindent the DSO is
also not printed. It's useful for some cases, so add an own DSO printout
for callindent for the case when IP/ADDR is not enabled.

Before:

% perf script --itrace=cr -F +callindent,-ip,-sym,-symoff,-addr

(in the kernel case of course it's not very useful, but it's important
with user programs where symbols are not unique)
