adb: add remount -R for deduplicated ext4

When using "adb remount" on a deduplicated filesystem, the current
response is a warning that the remount will not work. This patch
allows the user to specify an -R option. This option will reboot to recovery,
run e2fsck to undo deduplication, and then reboot the device where "adb
remount" will then succeed.

In addition, if verity needs to be disabled to remount, it will be disabled in
the same reboot cycle to minimize reboots.
