fs_mgr: adb-remount-test.sh: filter out more administrivia mounts.

binder /dev/binderfs binder rw,relatime,max=1048576,stats=global 0 0
/sys/kernel/debug /sys/kernel/debug debugfs rw,seclabel,relatime 0 0
/dev/block/dm-3 240548676 3692368 236856308   2% /data_mirror/cur_profiles

are administrative mounts uninteresting to the adb remount test.

Fix system and vendor devt tests, turn them into warnings instead.
