sudo: fix install

Running sudo on the target fails with the following errors.

  sudo: /usr/libexec/sudoers.so: No such file or directory
  sudo: fatal error, unable to load plugins

The problem is that the installation of the sudo package is broken. This patch
replaces the hand-crafted install rule with the default AUTOTARGETS install.

Unfortunately, the default install fails because it includes a step that
invokes the cross-compiled visudo binary. A patch is provided here to disable
this visudo invocation, which is for sanity checking only. This local patch is
a backport of upstream commit 8209:0c4e3f68b2f5; the real fix will be in the
1.8.6 release of sudo.

+The installation of the sudoers plugin fails when cross compiling, because it
+tries to run the cross-compiled visudo, rather than that of the host.
+
+The visudo invocation is only required in order to sanity check any existing
+sudoers file in the target directory; this can safely be dispensed with.
+
+This is a backport of commit 8209:0c4e3f68b2f5 from upstream.
+
+N.B. The upstream fix will appear in sudo 1.8.6; when the Buildroot package
+is bumped to version 1.8.6 (or higher), then this patch will no longer be
+required.
