ceph: require of e2fsprogs package

since we've switched to centos as default images it has revealed a bug
during ceph-disk prepare operation when deploying with dmcrypt
scenarios.

typical error:
```
......
get_dm_uuid: get_dm_uuid /dev/sda uuid path is /sys/dev/block/8:0/dm/uuid
get_dm_uuid: get_dm_uuid /dev/sda uuid path is /sys/dev/block/8:0/dm/uuid
get_dm_uuid: get_dm_uuid /dev/sda5 uuid path is /sys/dev/block/8:5/dm/uuid
populate: Creating lockbox fs on %s: mkfs -t ext4 /dev/sda5
command_check_call: Running command: /usr/sbin/mkfs -t ext4 /dev/sda5
mkfs.ext4: No such file or directory
Traceback (most recent call last):
  File "/usr/sbin/ceph-disk", line 9, in <module>
    load_entry_point('ceph-disk==1.0.0', 'console_scripts', 'ceph-disk')()
......
```

mkfs.ext4 is not found because the package `e2fsprogs` isn't installed.
It seems that ceph/ceph doesn't have a require for `e2fsprogs` so this
commit is a workaround until we can get this fixed in ceph/ceph.
(see: https://github.com/ceph/ceph/pull/21345/files)

Since this impacts several distributions and the package name is the
same for all, I've put this in `./src/daemon-base/__CEPH_BASE_PACKAGES__`.
We could remove this when it will have been fixed in ceph/ceph.
