db845c: move the normal fstab path to /vendor/etc/fstab.db845c

as it is required by the GetFstabPath funtion defined here:
    https://android.googlesource.com/platform/system/core/+/refs/heads/master/fs_mgr/fs_mgr_fstab.cpp#411

and the fstab.ramdisk.common does not need to be copied to vendor partition.

Test: boot up db845c with android-5.4 and android-mainline kernels, and tested with vts-kernel -m VtsKernelEncryptionTest
