            Log:
            Add sbin_compat bcond to rely on filesystem file triggers for sbin symlinks

Instead of shipping /usr/sbin symlinks directly in the RPM, rely on
filesystem(unmerged-sbin-symlinks) file triggers to create them at
install time. This avoids file conflicts when the package (built on an
unmerged system) is installed into a merged-sbin buildroot, eliminating
the bootstrap ordering problem with the bin/sbin merge.

On unmerged systems, the filesystem file trigger creates the symlinks
when files are installed to /usr/bin. On merged systems, /usr/sbin is
already a symlink to bin so no action is needed.

The bcond defaults to enabled. Use --without sbin_compat to revert to
the old behavior of shipping sbin symlinks in the package.
