perf script: Make printing of dso a separate field option

Browse Source 
The 'sym' option displays both the function name and the DSO it comes
from. Split the display of the dso into a separate option.  This allows
display of the ip address and symbol without the dso, thus shortening
line lengths - and decluttering the output a bit.

-f::
--fields::
Comma separated list of fields to print. Options are:
comm, tid, pid, time, cpu, event, trace, ip, sym. Field
comm, tid, pid, time, cpu, event, trace, ip, sym, dso. Field
list can be prepended with the type, trace, sw or hw,
to indicate to which event type the field list applies.
e.g., -f sw:comm,tid,time,ip,sym and -f trace:time,cpu,trace
