[PATCH RFC v7 3/8] security: Export security_inode_init_security_anon for KVM guest_memfd

KVM guest_memfd is implementing its own inodes to store metadata for
backing memory using a custom filesystem. This requires the ability to
initialize anonymous inode using security_inode_init_security_anon().

As guest_memfd currently resides in the KVM module, we need to export this
symbol for use outside the core kernel. In the future, guest_memfd might be
moved to core-mm, at which point the symbols no longer would have to be
exported. When/if that happens is still unclear.
