[LLDB] fix error message for one-line breakpoint scripts

LLDB is ignoring compilation errors for one-line breakpoint scripts.
This patch fixes the issues and now the error message of the
ScriptInterpreter is shown to the user.

I had to remove a new-line character for the Lua interpreter since it
was duplicated.
