OpenLDAP's first choice uuid functions are close to but not quite the same
as we have in libc, differences being that we don't have uuid_to_str() (in
fact I don't see which other OS might have it either, no other software in
Debian codesearch uses this), and it needs uuid.h not sys/uuid.h.
Patch to use it, avoiding the need for Linux/libext2fs libuuid.
