Since we don't need to update partitions separately, a single vbmeta is
enough for all partitions.

This CL fixes a series of mistakes which let the system and the vendor
partition be mounted without dm-verity.
* avb=vbmeta and avb=vbmeta_system flags are added to fstab so that the
partitions are mounted over dm-verity
* uboot script is modified to append avb_bootargs into bootargs so that
avb parameters like the root hash, etc. are passed to the kernel via
cmdline
* The boot partition is no longer a chained partition. Its hashtree is
included in vbmeta.img directly. This is firstly because we don't have a
need to update the kernel independently from other partitions. And
secondly, boot as a chained partition requires us to create
/dev/block/by-name/boot during the first stage init, which require
additional-but-useless entry in fstab.
* Name of the logical partitions in super.img is changed to system_a and
vendor_a from system and vendor, respectively.

For security reason, we will use tmpfs for /data. It should contain only
small, temporary files for now.
vold is removed as it's redundant now. MicrodroidTestCase's boot marker
is also updated because logd reinit won't happen if vold is removed.

For now, the default implementation will be used. In the future,
microdroid-specific keymint HAL will be implemented.
