Remove "class DriveInfo" (dead code)

[buhtz]

Always surfing through the codebase ... 🏄

The class DriveInfo was introduced in 2009 by Dan.

backintime/common/driveinfo.py

Line 25 in 5aa0746

class DriveInfo(configfile.ConfigFile):

Looking into the commit history it wasn't substantially modified.
But it was also never used (checked via git grep).

Code and idea behind should be investigated. There is not much documentation about it.

The class try to find out the features (permissions, hardlinks, ...) of the given file system.
And it seems to store the result as a config file.

I say it can be removed without replacement.

Dear SanjaySiddharth ,
thanks for this kind offer.
When scrolling up you might see that the issue was referenced in #1706 which itself is a Pull Request. So the Issue was taken by some one else and has a solution (#1706).

Let me know if you find something else.
