[Bug 1236233] [NEW] BIOS that SMIBIOS is not fuly supported by dmidecode causes image autmatic installation fail

[Hsin-Yi, Chen (hychen)]

Public bug reported:

Image: Ubuntu 12.04 LTS

The suffix of hostname is too long and makes ubiqutiy automatic installation failed
because suffix contains the warring message of dmidecode.

Here is the error message in /var/log/installer/debug when installtion
is failed.

Traceback (most recent call last):
  File "/usr/lib/ubiquity/plugins/ubi-usersetup.py", line 394, in info_loop
    self.hostname_error(make_error_string(self.controller, errors))
  File "/usr/lib/ubiquity/plugins/ubi-usersetup.py", line 69, in make_error_string
    return "\n".join([controller.get_string(error) for error in errors])
TypeError: sequence item 0: expected string, NoneType found

In automation installtion, ubiquity uses product name from BIOS as hostname suffix by 
parsing dmidecode output, but if a SMBIOS version is large thatn the version dmidecode supported,
the output of `dmidecode -s system-product-name` or `dmidecode -s system-version` 
contains the following warring message, so that hostname suffix is invalid.

The warring message is

````
# SMBIOS implementations newer than version 2.7 are not
# fully supported by this version of dmidecode.
````
