This change lets us use gc5035 camera, which was blocked by OnePlus long
time ago after people discovered its *magic* capabilities. By default
only `com.oem.autotest` can use it, however if we replace the first
character with a NULL byte, then strncmp returns 0, and thus we pass the
check and allow everyone to use it.
You can see the logs below that led me to discover that behavior.
