Commit ea9921f4f5b9 ("f2fs-tools: support zoned device in Android") in
f2fs-tools supports zoned device in Android. When detecting the disk
supports zoned device with proper types, we need to access its sysfs
entry. Note that, we need to check sysfs entries by default for
non-zoned disks in general as well.
If a product doesn't use metadata encryption which sets a device mapper, vendor
selinux needs to allow sysfs entries for raw disks such as sysfs_scsi_devices or
sysfs_devices_block.

To perform sdk sandbox data isolation, the zygote gets the selinux label
of SDK sandbox storage (e.g. /data/misc_{ce,de}/<user-id>/sdksandbox)
before tmpfs is mounted onto /data/misc_{ce,de} (or other volumes). It
relabels it back once bind mounting of required sandbox data is done.
This change allows for the zygote to perform these operations.

Currently, app process can freely execute path at
`/data/misc_ce/0/sdksandbox/<package-name>` since it's labeled as system
file. They can't read or write, but use 403/404
error to figure out if an app is installed or not.
By changing the selinux label of the parent directory:
`/data/misc_ce/0/sdksandbox`, we can restrict app process from executing
inside the directory and avoid the privacy leak.
Sandbox process should only have "search" permission on the new label so
that it can pass through it to its data directory located in
`/data/misc_ce/0/sdksandbox/<package-name>/<per-sdk-dir>`.

Remove references in sepolicy. Leave a few of the types defined since
they're public and may be used in device-specific policy.
