[Samba] [WIP][PATCH] 'fix' smbspool_krb5_wrapper, libexecdir and ctdb helper binary locations for 4.4

Thank you for writing the patch.

Maybe I am being picky or (most probably) ignoring some valid motive, 
but why does "smbspool_krb5_wrapper" need a "libexec" directory just for 
itself? Was there something wrong with keeping this file in 
"/usr/local/samba/bin" as it happened with samba 4.3.6? Why complicate 
the tree?
