[PATCH] lib/test_firmware: add header file to prevent build errors

[Randy Dunlap]

From: Randy Dunlap <rdunlap@xxxxxxxxxxxxx>

lib/test_firmware.c has build errors on some $ARCH due to a
missing header file, so add it.

  lib/test_firmware.c:134:2: error: implicit declaration of function 'vfree' [-Werror=implicit-function-declaration]
  lib/test_firmware.c:620:25: error: implicit declaration of function 'vzalloc' [-Werror=implicit-function-declaration]
