modpost: distinguish same module paths from different dump files
Since commit 13b25489b6f8 ("kbuild: change working directory to external
module directory with M="), module paths are always relative to the top
of the external module tree.
The module paths recorded in Module.symvers are no longer globally unique
when they are passed via KBUILD_EXTRA_SYMBOLS for building other external
modules, which may result in false-positive "exported twice" errors.
Such errors should not occur because external modules should be able to
override in-tree modules.
To address this, record the dump file path in struct module and check it
when searching for a module.
Fixes: 13b25489b6f8 ("kbuild: change working directory to external module directory with M=")
