user/horizon: Add upstream patch for PPC32 disks

This is required to partition PPC32 disks correctly when blank.
Otherwise, users will face the dreaded error:

```
/etc/horizon/installfile:8: error: partition: consistency error on
/dev/sda: Partition #1 has been requested, but the disk has 1 partitions
```

This fixes that issue.

+Subject: [PATCH] Qt UI: Count APM partitions correctly on PPC32
+
+The fix we did in 5df1abdb74 is not complete; we use APM on 32-bit
+PowerPC machines as well.  We need to do the same workaround on PPC32
+that we do on PPC64 Power Macs.
+
+Fixes: 5df1abdb74 ("Qt UI: Fix partition count for APM disklabel")
