This fixes a few obvious issues when comparing the make dist output with
the git tree.

 - Make all templates non-executable in git
 - Remove unused files:
   - src/lxc/list.c (empty, only includes the list.h header)
   - src/lxc/lxc-destroy.in (replace by lxc_destroy.c)
 - Add missing files to dist tarball:
   - src/python-lxc/examples/pyconsole.py
   - src/python-lxc/examples/pyconsole-vte.py
 - Mark all the python API tests executable
 - Mark lxc-test-ubuntu executable
