Add logo and colours for Adélie Linux, and for Tru64 UNIX

[mc680x0]

Description

This adds logos and colours to neofetch for the Adélie Linux distribution, and because I didn't split it to a different set of commits (silly me), lays the groundwork for supporting Tru64 / Digital UNIX / OSF/1 that I intend to further flesh out at a future point (read: when I can test any changes more complex than I've made thus far).

Relevant Links

The old upstream neofetch had support requested for Adélie, but it never got merged in.

Looks good!

Also, I just properly escaped backslashes for you so that the col length is calculated correctly:

Amazing, thanks very much for the fixes. Escaping always catches me up in large chunks of shellscript.
