Prevent netifaces from introducing netmasks in the form of 'ffff::/16'.
Once this has been applied everywhere, all other fixes for this can be
dropped.

Currently computer netmask looks like 'ffff::/16' in slapos.xml.
With this commit, this netmask will be cleaned up to just 'ffff::'.

Computer definition file (slapformat-configuration.cfg) may now have:

```
[partition_0]
...
capability_list =
  fast-network
  more_disk_space
  yet another capability

...
```

Capabilities are line-separated and may otherwise contain whitespace.
Whitespace at the beginning and end of each line is stripped.

Previous code matched way too many files as belonging to the current
partition and wrongly removed them as obsolete: e.g. when processing
slappart1, all the configuration files belonging to slappart10 would
systematically be deleted, as if they belonged to slappart1 and were
now out-of-date. Same for all partitions starting with 'slappart1',
such as slappart11, slappart12, etc.

This resulted in all services in slappart1X being stopped and started
repeatedly and very often: stopped during processing of slappart1 and
started during processing of slappart1X, with potentially several
minutes of downtime, and a high percentage of downtime.

This is a fixup of db98a521.

This method is important we want to test it
