See #1293

* Fix hardening if backtraces are off
* Ensure that all tests are passed with hardened flags
* RPM: add --with/--without backtrace option (default is --with)
* RPM: remove dependency on libbfd, libiberty, libz if --without backtrace
* RPM: enable stripping and debuginfo if --without backtrace

Backtraces are still enabled by default.

Hardened flags used by RedHat:

  -Werror=format-security -Wp,-D_FORTIFY_SOURCE=2
  -fstack-protector-strong --param=ssp-buffer-size=4
  -pie -fPIC

xxx-common packages is Debian style.
RPM usually doesn't use separate packages for init scripts.

A prerequisite for proper #1085 fix

This patch also enables daemon supervision when used with systemd.
A prerequisite for Fedora/EPEL7 packages.

to comply with policies and packaging guidelines [1]. Please don't push
to this file before getting a review from somebody who is familiar with

I've checked that packages actually work on Fedora Rawhide (systemd) and
CentOS 6 (sysvinit). It should be safe to switch our builds to the new
spec and remove old one after fixing problems with tarantool/build [2][3].

This is a workaround for #1262

* Add -DENABLE_DIST=ON option to enable init scripts on `make install`
* Create directories for tarantoolctl on `make install`
* Add logrotate script to `make install`
* Fix example.lua to work out of the box
* Use /etc/default instead of /etc/sysconfig on Debian
* Fix directories permissions for tarantoolctl
* Add support for systemd-tmpfiles (required by Fedora)

Unfortunally, I was unable to test it before pushing due to buggy
tarantool/build.

Needed for Fedora buildbot
