scripts/release: make the script more robust, and release a source repository snapshot

Browse Source 
Following Petr Lautrbach's suggestion, release a snapshot of the source
repository next to the individual archives which constitute a release.

While at it, make scripts/release more robust:

- Fix many warnings reported by shellcheck, by quoting strings.
- Use bash arrays for DIRS and DIRS_NEED_PREFIX
- Merge DIRS and DIRS_NEED_PREFIX into a single array, in order to
  produce SHA256 digests that are directly in alphabetical order, for
  https://github.com/SELinuxProject/selinux/wiki/Releases
- Use "set -e" in order to fail as soon as a command fails
- Change to the top-level directory at the start of the script, in order
  to be able to run it from anywhere.
- Use `cat $DIR/VERSION` and `git -C $DIR` instead of `cd $i ; cat VERSION`
  in order to prevent unexpected issues from directory change.

Finally, if version tags already exists, re-use them. This enables using
this script to re-generate the release archive (and check that they
really match the git repository). Currently, running scripts/release
will produce the same archives as the ones published in the 3.2-rc1
release (with the same SHA256 digests as the ones on the release page,
https://github.com/SELinuxProject/selinux/wiki/Releases). This helps to
ensure that the behaviour of the script is still fine.
