Fix vendor.img creation failing with latest build_image script

Latest build_image script used to build vendor.img expects the file
paths in the format folder_path/file_name whereasiwlwifi firmware copy
script provides the path firmware/./iwlwifi* resulting in build_image
failing with firmware/./iwlwifi-100-5.ucode: not normalized.

Modified the find option to fix the path issue.

Tests done:
- Android boot with GVT-d and BM
- Wi-Fi on/off/scan/connect/disconnect
- adb reboot
