CLI: fixed creation of perun-cli.tar.gz

- Fixed creation of perun-cli.tar.gz archive from CLI sources, since
  version from November 2013 was copied to AFS on every build
  (because of wrong file name).

- Added execution mark (+x) to CLI commands, which missed it.
Merge pull request #400 from zlamalp/cli
