selftests/mm: fix thuge-gen test name uniqueness

The thuge-gen test_mmap() and test_shmget() tests are repeatedly run for a
variety of sizes but always report the result of their test with the same
name, meaning that automated sysetms running the tests are unable to
distinguish between the various tests.  Add the supplied sizes to the
logged test names to distinguish between runs.

My test automation was getting pretty confused about what was going on
- the test names are a pretty important external interface.
