Description of the change

1) Adds SMBIOS28_JUNK module variable for better readability when using this value within dmimodel().

2) Changes dmimodel() to check if the resulting model starts with SMBIOS28_JUNK, and if so, to strip this prefix.

The comment above SMBIOS28_JUNK provides an explanation, and this bug provides more background:

In the future, I do wonder if it might be better for Ubiquity to get these values from /sys/class/dmi/id/*.
