gvfs patch to remove lsof dependency [review D56224]

Hi,

As subject states I have prepared a patch to gvfs that removes the need 
to have lsof installed, replacing its usage with fuser(1), which is 
included in the base system. [1]

I was moved into doing this after lsof broke (again) on head.

There is a single use of lsof in gvfs, for which the port forces any 
desktop machine to depend on lsof. So I think this could be a very good 
improvement for our ports tree, removing this extra dependency, for a 
very single and minor use.

I also sent the patch upstream [2], so if anyone has contacts there and 
can push for it or at least get some feedback that would be very helpful!

Anyway, I am usually against diverging from upstream, but in this case I 
think the advantages are strong enough to warrant an exception.

So I'm asking if anyone from gnome@ could approve this change.

Thanks in advance!
