clean up stale conditionals

All but two of the `%if 0%{?fedora} >= 15 || 0%{?rhel} >= 7`
conditionals were removed in 76c7fad (Fix systemd
executions/requirements, 2018-01-25).  Remove the others.

Remove Fedora version from `%if 0%{?fedora} > 27 || 0%{?rhel} > 7`.
Fedora 27 has been EOL since 2018-11-30.
