Tramp brocken selinux support: can't safe file.

[Sascha Wilde]

Hi,

in the current trunk I can't safe remote files in tramp.  It errors out
with a miss matching number of arguments for a copy-file operation.  The
following quick and dirty hot fix makes it work for me again, but I'm
110% positive that it is incomplete and most likely totally wrong:

I use (setq backup-by-copying t) -- not sure if its related.
