[cmake] add missing dependency lldbCommands->lldbBase

CommandObjectVersion.cpp calls lldb_private::GetVersion (present in lldbBase).

This should fix the unittest link on windows. I am not sure why is this not
present on other platforms -- my guess is that there lldbBase is included in
the link through some other dependency chain.
