libusbgx: check scripts in /etc/usbgx.d

Sometimes an end user might want to change some values in
/sys/kernel/config/usb_gadget/ at runtime, for instance, a product id
or serial number must be read from /proc/device-tree, and so on.

Support that by letting gadget-start run all scripts in /etc/usbgx.d
after importing the schemas.
