Special runCmd() for build perf tests which doesn't raise an
AssertionError when the command fails. This causes command failures to
be detected as test errors instead of test failures. This way "failed"
state of tests is reserved for future making it possible to set e.g.
thresholds for certain measurement results.

The new class is derived from unittest.TextTestResult class. It is
actually implemented by modifying the old BuildPerfTestRunner class
which, in turn, is replaced by a totally new simple implementation
derived from unittest.TestRunner.

Rename BuildPerfTest to BuildPerfTestCase and convert it to be derived
from TestCase class from the unittest framework of the Python standard
library. This doesn't work with our existing testcases or test runner
class and these need to be modified, too.

The new class is responsible for actually running the tests and
processing their results. This commit also adds a decorator function for
adding new tests. No automatic test discovery, at least yet.

The new class will be used as an abstract base class for build
performance tests. This implementation contains some common
functionality used in multiple tests, "copied" from the
build-perf-test.sh shell script.

Add a new utility class for dropping Linux kernel caches. It uses sudo
and tee to write to the drop_caches file. Checking if the user has the
permissions to drop caches (without a password) is done by trying to
writing an invalid value to the drop_caches file. This way, we will find
if writing (with tee) is possible but not really dropping caches, yet.
User can avoid giving the password by adding something like:
<user> ALL = NOPASSWD: /usr/bin/tee /proc/sys/vm/drop_caches
to the system sudoers file.
