var/loop/find: detect/reject bug in 'find' on HP-UX B.11.11

On (at least) this HP-UX version, the standard 'find' utility
cannot correctly handle multiple '-exec ... {} +' primaries.

Among other things, this needs to function if loop iterations
(which depend on one such -exec) are combined with the use of a
literal '-exec ... {} +' in a find loop.

lib/modernish/mdl/var/loop/find.mm:
- init: Reject 'find' utilities with the bug described above.
