Unexpected /module_info.ld in kernel-signed build stage

[christopherco]

Describe the bug
When building any kernel-signed package, the module_info.ld file is produced, which is unexpected. This then causes installed but unpackaged file errors
“Installed (but unpackaged) file(s) found: /module_info.ld"

The module_info.ld file has been excluded in the packaging list, but opening this issue to track down the precise behavior here
 
To Reproduce

1. Remove the %exclude /module_info.ld entry from kernel-signed spec
2. rpmbuild the kernel-signed spec
   Observe error during rpmbuild

Expected behavior
No rpmbuild error when building the kernel-signed spec

Screenshots
rpmbuild output

“Installed (but unpackaged) file(s) found: /module_info.ld"
