Masahiro Yamada dc92ac9f63 rust: replace <linux/module.h> with <linux/export.h> in rust/exports.c
<linux/export.h> is the right header to include for using
EXPORT_SYMBOL_GPL. <linux/module.h> includes much more bloat.

*
* This requires the Rust's new/future `v0` mangling scheme because the default
* one ("legacy") uses invalid characters for C identifiers (thus we cannot use
* the `EXPORT_SYMBOL_*` macros).
*
* All symbols are exported as GPL-only to guarantee no GPL-only feature is
* accidentally exposed.
