topjohnwu e0927cd763 Add support to patch QCDT
Old Qualcomn devices have their own special QC table of DTB to
store device trees. Since patching fstab is now mandatory on Android 10,
and for older devices all early mount devices have to be included into
the fstab in DTBs, patching QCDT is crucial for rooting Android 10
on legacy devices.

Close #1876 (Thanks for getting me aware of this issue!)
