This is in line with the change of mkuserimg_mke2fs.sh to python binary.

Support a first stage ramdisk which will include the targets placed
into TARGET_RAMDISK_OUT. This replaces the existing ramdisk on
existing devices.
All system images are now built to be mounted as the root dir.
Devices with a first stage ramdisk will switch root to the system
partition.
BOARD_BUILD_SYSTEM_ROOT_IMAGE remains and is used to specify if the
system partition is going to be directly used as rootfs without the
ramdisk.

When building a system image with system_root_image enabled, the size
computation should include files under both of in_dir (i.e. /system
files) and root (pointed by 'root_dir'). Because files from both
locations will end up into the built image. The files under root are
usually only a few MiBs, but should be accounted for especially in the
context of logical partitions (where the partition size will be
allocated based on the actual need). Note that we will still need some
"reserved space" (defined via BOARD_*_PARTITION_RESERVED_SIZE) to cover
the cost for filesystem and/or verity metadata.
This CL moves the combination of the two dirs up, before parsing and
computing other properties. This doesn't affect anything for a
successful image building path. It may however increase the time to
error out in certain error path, since it copies the files earlier now.
Test: python -m unittest test_build_image
Test: `make dist`
Test: Setup a target with PRODUCT_USE_LOGICAL_PARTITIONS == true and
BOARD_SYSTEMIMAGE_PARTITION_RESERVED_SIZE == 20MiB. Build system
image successfully.
Test: Setup a target with PRODUCT_USE_LOGICAL_PARTITIONS == true and
BOARD_SYSTEMIMAGE_PARTITION_RESERVED_SIZE == 20MiB. Write a large
file to root dir (PRODUCT_OUT_ROOT). The image building fails, but
reporting a size that accounts for both of /system and root.

The test is mostly trivial, but it ensures the result parsing from
actual calls to mke2fs.
Test: python -m unittest test_build_image
Test: `m dist` on aosp_marlin-userdebug (w/ and w/o defining
PRODUCT_SYSTEM_HEADROOM respectively).
