Deployment updates due to EPEL 7 and Debian 9/sid.

1) os_type used only for startup/boot type,
   "fedora" replaced by "systemd" (systemd can be used across distributions)
2) workaround detection problem of EPEL 7
3) removed automatic detection of mysqlconfdir (solved only inside packages now)
4) new configure option --sysdefaultdir (typical values /etc/sysconfig or /etc/default)
Update source tarball file lists.
