sudo: fix multilib conflict

It fails to install sudo and lib32-sudo at same time:

| Error: Transaction test error:
|  file /usr/libexec/sudo/audit_json.so conflicts between attempted
     installs of lib32-sudo-1.9.3p1-r0.core2_32 and sudo-1.9.3p1-r0.core2_64
|  file /usr/libexec/sudo/group_file.so conflicts between attempted
     installs of lib32-sudo-1.9.3p1-r0.core2_32 and sudo-1.9.3p1-r0.core2_64

Pass ${libdir} to configure option --libexecdir of sudo that it installs
plugin libraries to /usr/lib{,64} rather than /usr/libexec/. Then add a
patch to fix multilib conflict of sudo.conf.

+sudo.conf.in: fix conflict with multilib
+
+When pass ${libdir} to --libexecdir of sudo, it fails to install sudo
+and lib32-sudo at same time:
+
+| Error: Transaction test error:
+|  file /etc/sudo.conf conflicts between attempted installs of
+     sudo-1.9.3p1-r0.core2_64 and lib32-sudo-1.9.3p1-r0.core2_32
+
+Update the comments in sudo.conf.in to avoid the conflict.
