[LLDB] Add missing newline to "image lookup" output

[DavidSpickett]

Summary

When using --name, due to a missing newline, multiple symbol results
were not correctly printed:

(lldb) image lookup -r -n "As<.*"
2 matches found in <...>/tbi_lisp:
        Address: tbi_lisp<...>
        Summary: tbi_lisp<...> at Symbol.cpp:75        Address: tbi_lisp<...>
        Summary: tbi_lisp<...> at Symbol.cpp:82

It should be:

(lldb) image lookup -r -n "As<.*"
2 matches found in /home/david.spickett/tbi_lisp/tbi_lisp:
        Address: tbi_lisp<...>
        Summary: tbi_lisp<...> at Symbol.cpp:75
        Address: tbi_lisp<...>
        Summary: tbi_lisp<...> at Symbol.cpp:82

With Address/Summary on separate lines.
