tests: fix the memcheck test
The file was raising due to the undefined constant `verifiers`, leading
the test to be ignored.
./main.py list -v
would show this as:
```
Traceback (most recent call last):
File "/gem5/tests/../ext/testlib/loader.py", line 239, in load_file
execfile(path, newdict, newdict)
File "/gem5/tests/gem5/memcheck/test_memcheck.py", line 32, in <module>
verifiers=verifiers,
NameError: name 'verifiers' is not defined
Exception thrown while loading "/gem5/tests/gem5/memcheck/test_memcheck.py"
Ignoring all tests in this file.
```
The test has been modified to have an empty verifiers list, which should
still catch bugs since src/mem/mem_checker.cc has several asserts already
which would be caught by the test system due to the exit status.
Also make the following changes to the test:
- move it to tests/gem5/memory/test.py with other memory tests.
This makes it easier to see all the tests in the source in one go, and
might make it easier to factor certain memory things out later on.
- reduce --maxtick to a value that finishes in 7 seconds on a Lenovo
ThinkPad P51.
The previous value would take 50x longer, which feels too long for a
single test.
- enable --prefetchers to also stress a prefetcher in the test
