dfu:tests: Modify dfu_gadget_test.sh to accept USB device vendor:product ID

dfu-util allows filtering on USB device vendor:product ID by using
the -d flag (-d 0451:d022).
Such option is very handy when many DFU devices are connected to a single
host PC. This commit allows testing when above situation emerges.

 They can be obtained from dfu-util -l or $dfu_alt_info.
 It is also possible to pass optional [test file name] to force the script to
 test one particular file.
+If many DFU devices are connected, it may be useful to filter on USB
+vendor/product ID (0451:d022).
+One can get them by running "lsusb" command on a host PC.
