cgitrc.5: tar.xz is a supported snapshot format

When tar.xz support was added in 0642435fed (2009-12-08: Add
.tar.xz-snapshot support), cgitrc.5 was not updated to match. This
patch fixes the issue.

 	non-bare repos. This must be defined prior to scan-path.

 scan-path::
 	A path which will be scanned for repositories. If caching is enabled,

 	repositories to match those exported by git-daemon. This option MUST come
 	before 'scan-path'.
 
 virtual-root::
 	Url which, if specified, will be used as root for all cgit links. It
 	will also cause cgit to generate 'virtual urls', i.e. urls like
 	'/cgit/tree/README' as opposed to '?r=cgit&p=tree&path=README'. Default

 	NOTE: cgit has recently learned how to use PATH_INFO to achieve the
 	same kind of virtual urls, so this option will probably be deprecated.
