testsdk: allow user to specify which tests to run

Following the usage of TEST_SUITES in testimage, add TESTSDK_SUITES to
specify the list of tests to execute. By default the variable is empty,
which means to run all discovered tests.

This makes it easier to work on a single test without having to run all
of the tests.
