SELinux: add selinux_kernel_module_request

This patch adds a new selinux hook so SELinux can arbitrate if a given
process should be allowed to trigger a request for the kernel to try to
load a module.  This is a different operation than a process trying to load
a module itself, which is already protected by CAP_SYS_MODULE.
