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.

This adds a line break between each result address in the output of the
lldb command `target modules lookup`. Before this change, a new address
result will be printed on the same line as the summary of the last
result, making the output difficult to view.
Also adds a test for this command.
