small patches for ZSH Completion function

[Baptiste Daroussin <daroussi@xxxxxx>]

Hi,

The following patches are for :

chown: 
	add linux to the OSTYPE that need suffix : after users because 	the
suffix . is deprecated and in the last version of chown on 	my gentoo
does not work anymore.
links: 
	added a _call_program to get a list of available drivers for 	-driver
option
mplayer: 
	added the new matroska (mkv mka) format in list (supported since 	the
1.0pre2 version of mplayer) and ogm, ogg (supported since 	??)

hope it helps (this time I've made patches :) )
