Since there's no two separate mount namespace, we don't need to
"enter_default_mount_ns".

These nodes are not meaningful in Microdroid, but added here in order to
satisfy the existing code that tries to put a PID to one of the cpusets.

com.android.sdkext is to decide the extension SDK level of the device
and set system properties so that apps can query it.
In microdroid we don't support it yet. So remove it from the mandatory
system APEX list.

KeyMint in microdroid will initially be a specialized version of the
software KeyMint reference implementation. Begin this specialization by
removing the services that aren't needed within VMs.

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.

zipfuse now runs in microdroid as a service. The source zip file path
and the mount point are fixed to /dev/block/by-name/microdroid-apk and
/mnt/apk, respectively.
To support that, microdroid_payload.json is amended to add
MicrodroidTestAppk.apk to the payload.img file. This eventually should
be done dynamically by the virt manager.

/data/anr is technically also redundant, but we have to fix tombstoned

Many programs need /data (especially /data/local/tmp) to properly work.
This change adds a basic unencrypted ext4 userdata partition to
microdroid. Eventually microdroid will support userdata encryption so
only VM can access /data.

Host apexes are passed to microdroid via the payload composite image.
The payload composite image can be created by either
mk_payload_signature/mk_cdisk or mk_payload.
For now, microdroid expects two APEXes from the host:
- com.android.adbd
- com.android.sdkext
The exact set of host apexes for microdroid is TBD. The current set is
only for demonstration.

Previously, we ran only 'apexd-bootstrap' because 'apexd' crashes due to
the lack of /data/apex in microdroid.
Now apexd runs in "vm" mode. In vm mode, apexd only activates built-in
apexes and block apexes. No data apexes, no session handling.

The following system properties are forcibly set to make adbd function.
ro.apex.updatable=true : otherwise, apexd doesn't activate critical
APEXes like the runtime APEX
ro.adb.secure=0 : to bypass the adb authentication
ro.debuggable=1 : to be able to use ro.adb.secure=0
