Description of problem:

sosreport's xen module copies all files in /etc/xen, including subdirectories and links.  There are links in the /etc/xen/auto directory linking up one level to the xen configuration files in /etc/xen, like so:

[root@defiant ~]# ls -la /etc/xen/auto/dg
lrwxrwxrwx 1 root root 5 Oct 22 08:57 /etc/xen/auto/dg -> ../dg

If sosreport is executed from /root, the python routine self.addCopySpec("/etc/xen") will attempt to copy anything in the ../dg directory, relative to where the command is executed.  So if, for instance, you had a xen config file called usr in /etc/xen, and a link to ../usr in /etc/xen/auto, sosreport executed in /root will attempt to copy all of /usr into /tmp.  With unwanted results.

Version-Release number of selected component (if applicable):


How reproducible:

Consistent.

Steps to Reproduce:
1.  touch /etc/xen/usr 
2.  cd /etc/xen/auto
3.  ln -s ../usr .
4.  cd
5.  sosreport --no-multithread -o xen -vvv
  
Actual results:

copying file ../usr/local/lib/libol.a
copying file ../usr/local/lib/pkgconfig/eventlog.pc
copying file ../usr/local/lib/libevtlog.a
copying file ../usr/local/lib/libol.la
copying file ../usr/local/lib/libevtlog.so.0.0.0
copying file ../usr/local/lib/libol.so.0.0.0

etc.

Expected results:
