[Cdash] Test memory consumption reported on CDash

[Olivier Pierard]

Thank you Andreas.

I tried it this morning and it works.

Now, I will also have a look at:
- Automatic computation of memory cost with CTest (as done for clock
time); but it seems quite difficult to do it in a portable way;
- Additional columns in CDash for the test list of a given build
(additional columns with 'max. memory status' and 'max. memory').
