Subject: [PATCH] Fix %post and %postun generation in kmodtool

During zfs-kmod RPM build, $(uname -r) gets unintentionally evaluated on
the build host, once and for all. It should be evaluated during the
execution of the scriptlets on the installation host. Escaping the $
character avoids evaluating it during build.
