Fix odm privapp permissions

SystemConfig.java treats permissions for odm and vendor priv-apps
identically, reading them into mVendorPrivilegedAppAllowlist.

Similarly, PermissionManagerServiceImpl.java should verify permissions
for pkg.isOdm() the same way as it does for pkg.isVendor(). Without this
fix, permissions for /odm/priv-app are simply ignored.
