[PATCH RFC tools/lkmm 09/12] tools/memory-model: Add required herd7 version to README file

[Paul E. McKenney]

LKMM and the herd7 tool are co-evolving, and out-of-date herd7 tools
produce inaccurate results, often with no obvious error messages.  This
commit therefore adds the required herd7 version to the LKMM README file.

Longer term, it would be good if .cat files could specify the required
version in a manner allowing herd7 to produce clear diagnostics.
