Subject: [PATCH] BTF: Don't break ABI when debuginfo is disabled.

Patch-mainline: Never, SUSE-specific

References: jsc#SLE-18805

Disabling BTF removes a member from struct modinfo breaking ABI all over

the place. We expect that disabling debuginfo builds the same kernel but

with BTF disabling debuginfo also disables BTF causing this brekage.

Simply include the BTF member in struct modinfo always.
