befs: remove trailing whitespaces

Removing all trailing whitespaces in befs.

I was skeptic about tainting the history with this, but whitespace changes
can be ignored by using 'git blame -w' and 'git log -w'.

Linux-2.6.12-rc2

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
