Call apexd --unmount-all at the end of otapreopt_chroot run
We don't really care for the umount part, but we do care about freeing
up loop and dm block devices so that next run of otapreopt_chroot can
re-use them.
Note that we must run `apexd --unmount-all` inside otapreopt_chroot
itself. This is because otapreopt_chroot runs in /postintall namespace.
Test: install an OTA, check number of loop devices
Test: Install an OTA, cancel during finalization, Restart OTA
Test: forrest test -l remote --test_bench_config asit/crosshatch --extra_args '--delegated-tf ab://tradefed/tradefed/P21446393/.*google-tradefed.zip?unzip=true' ab::P21523880:aosp_crosshatch-userdebug:git_master asit/dexoptota/self_full
