Subject: [PATCH] tdb2: test: Speed up run-01-new_database.

Don't run tdb_check with failtest on, since it is very slow.  Do the
tdb_check w/ failtest in a new test, but skip MMAP suppression which
doesn't add much and slows down valgrind a lot.

Before this change run-01-new_database took 40 seconds (under
valgrind), after it takes 8 seconds, and run-12-check takes 3
seconds).
