test_bpf: add module parameters to filter the tests to run.
When developping on the interpreter or a particular JIT, it can be
interesting to restrict the tests list to a specific test or a
particular range of tests.
This patch adds the following module parameters to the test_bpf module:
* test_name=<string>: only the specified named test will be run.
* test_id=<number>: only the test with the specified id will be run
(see the output of test_bpf without parameters to get the test id).
* test_range=<number>,<number>: only the tests within IDs in the
specified id range are run (see the output of test_bpf without
parameters to get the test ids).
Any invalid range, test id or test name will result in -EINVAL being
returned and no tests being run.
