SPDX-license-identifier-GPL and SPDX-license-identifier-W3C are
false positives in the detector in binary files.

libs/usb/test/accessorytest/f_accessory.h is an original kernel
header file with GPL 2.0 license. Replace it with the file from
libs/usb/tests/AccessoryChat/accessorychat/linux/usb/f_accessory.h,
which is the same header after running it through bionic's script
to remove copyrightable information from the header.

Move CPL license into test-runner/ and test-base/ where it is
used.

Test: m checkbuild
