usertools: fix binding built-in kernel driver

Browse Source 
A driver can be loaded as a dynamic module or a built-in module.
In commit 681a672886 ("usertools: check if module is loaded
before binding"), the script only checks modules in /sys/module/.

However, for built-in kernel driver, it only shows up in /sys/module/,
if it has a version or at least one parameter. So add check for
modules in /lib/modules/$(uname -r)/modules.builtin.

Fixes: 681a672886 ("usertools: check if module is loaded before binding")
