Subject: [PATCH] tools/memory-model: Update required version of herdtools7

Code generated by klitmus7 version 7.48 doesn't compile with kernel
header of 4.15 and later due to the absence of ACCESS_ONCE().
As the issue has been resolved in herdtools7 7.49, bump the required
version number in README.

Hi Paul,

I think this is a 4.17 matter.
Thoughts?

        Thanks, Akira
