Improve handling of undecrypted encrypted /data

- Until the encrypted partition is decrypted, treat it as a disk image
  instead of a filesystem so that it is properly backed up using dd.
- Make Partition::Wipe() use the filesystem from fstab for disk images
  so that wiping an undecrypted /data makes it a plain unencrypted
  partition again.

Work around MEMERASE ioctl for rk3066 compatibility

Due to a kernel bug and no available sources we have to work around the
MEMERASE ioctl - if used, it hangs and never returns. I straced the original
recovery executable and could see that it is simply calling write() with a
bunch of zeroes instead of using MEMERASE.

Added a hack that does the same and now the resulting TWRP recovery image works.

Add mode when open(O_CREAT) is used.

When creating a new file using open(..., O_CREAT), it is an error
to fail to specify a creation mode. If a mode is not specified, a
random stack provided value is used as the "mode".

This will become a compile error in a future Android change.
