[Bug 831319] [NEW] Ubiquity allows invalid group name

[Jean-Baptiste Lallement]

Public bug reported:

If the username is longer than 32 characters the installation will fail
with:

Adding user `eca40a93-4fbd-47d5-b084-8945a5499788' ...
Adding new group `eca40a93-4fbd-47d5-b084-8945a5499788' (1003) ...
groupadd: 'eca40a93-4fbd-47d5-b084-8945a5499788' is not a valid group name
adduser: `/usr/sbin/groupadd -g 1003 eca40a93-4fbd-47d5-b084-8945a5499788' returned error code 3. Exiting.

Ubiquity should limit the username length to 32 character to avoid this
failure.
