Allow apps in /odm/app and /odm/priv-app

/odm is a vendor partition other than /vendor. Both partitions are for
HW-specific modules such as HALs. The difference is that /odm is owned
by ODM (usually device manufacturer which designs the board), whereas
/vendor is owned by SoC manufacturer. In other words, /odm partition is
for board-specific customization to the /vendor partition.

Since apps can exist in /vendor/app and /vendor/priv-app, the same has
to be supported for /odm partition.
