bootstd: android: Add missing NULL in the avb partition list

When booting an Android build with AVB enabled, it's still possible to
deactivate the check for development purposes if the bootloader state is
UNLOCKED.

This is very useful for development and can be done at flashing time via:
$ fastboot flash --disable-verity --disable-verification vbmeta vbmeta.img

However, with bootmeth_android, we cannot boot this way:

    Scanning bootdev 'mmc@fa10000.bootdev':
      0  android      ready   mmc          0  mmc@fa10000.bootdev.whole
    ** Booting bootflow 'mmc@fa10000.bootdev.whole' with android
    avb_vbmeta_image.c:188: ERROR: Hash does not match!
    avb_slot_verify.c:732: ERROR: vbmeta_a: Error verifying vbmeta image: HASH_MISMATCH
    get_partition: can't find partition '_a'
    avb_slot_verify.c:496: ERROR: _a: Error determining partition size.
    Verification failed, reason: I/O error occurred while trying to load data
    Boot failed (err=-5)
    No more bootdevs

From the logs we can see that avb tries to read a partition named '_a'.
It's doing so because the last element of requested_partitions implicitly is
'\0', but the doc explicitly request it to be NULL instead.

Add NULL as last element to requested_partitions to avoid this problem.
