dynamic_debug: add wildcard support to filter files/functions/modules
Add wildcard '*'(matches zero or more characters) and '?' (matches one
character) support when qurying debug flags.
Now we can open debug messages using keywords. eg:
1. open debug logs in all usb drivers
echo "file drivers/usb/* +p" > <debugfs>/dynamic_debug/control
2. open debug logs for usb xhci code
echo "file *xhci* +p" > <debugfs>/dynamic_debug/control
