Subject: fedora: Refresh SELinux labels in scriptlets, require -selinux
 package

Instead of:
  https://fedoraproject.org/wiki/SELinux_Policy_Modules_Packaging_Draft

follow this:
  https://fedoraproject.org/wiki/PackagingDrafts/SELinux_Independent_Policy

which seems to make more sense and fixes the issue that, on a fresh
install, without a reboot, the file contexts for the binaries are not
actually updated.

In detail:

- labels are refreshed using the selinux_relabel_pre and
  selinux_relabel_post on install, upgrade, and uninstall

- use the selinux_modules_install and selinux_modules_uninstall
  macros, instead of calling 'semodule' directly (no functional
  changes in our case)

- require the -selinux package on SELinux-enabled environments and if
  the current system policy is "targeted"
