perf script: Allow sym and dso without ip, addr

Currently sym and dso require printing ip and addr because the print
function is tied to those outputs. With callindent it makes sense to
print the symbol or dso without numerical IP or ADDR. So change the
dependency check to only check the underlying attribute.

Also the branch target output relies on the user_set flag to determine
if the branch target should be implicitely printed. When modifying the
fields with + or - also set user_set, so that ADDR can be removed. We
also need to set wildcard_set to make the initial sanity check pass.

This allows to remove a lot of noise in callindent output by dropping
the numerical addresses, which are not all that useful.
