With CONFIG_TRIM_UNUSED_SYMS, if a module has enough dependencies to exceed the default xargs command line size limit, the output is split into multiple lines, which can result in used symbols getting trimmed. This change removes duplicate dependencies, which will reduce the probability of this happening and makes .mod files smaller and easier to read.
