Subject: [PATCH] ivi-controller: fixed string copy in controller_screen_screenshot

From: Mateusz Polrola <mateuszx.potrola at intel.com>

With earlier implementation memory for NULL byte of l->filename string was not being allocated by malloc (strlen is returning length of string without NULL terminating byte) which may result in some random characters appended in filename string.
Now strdup is begin used for string copy instead of malloc/strcpy.
