meta-facebook: bletchley: switch the emmc mount to /mnt/emmc

Internal code has switched over to handle both `/mnt/emmc` or as a
fall-back `/mnt/data`.  Move the eMMC mount location to `/mnt/emmc`
and remove the extra symlinks.

Tested: Observed on QEMU the desired mounts.
```
root@bletchley:~# mount | grep "on /mnt"
overlay on /mnt/data type overlay (rw,relatime,lowerdir=/mnt/data,upperdir=/run/mnt-persist/mnt/data-data,workdir=/run/mnt-persist/mnt/data-work,uuid=on)
/dev/mmcblk0 on /mnt/emmc type btrfs (rw,relatime,compress=zstd:3,ssd,discard,noacl,space_cache=v2,subvolid=5,subvol=/)
```
