These constants are available in the config package already and do not
need to be re-exported under a different name.

This reduces the API exposed by the pkg/bpfassets and
also makes it easier to test.

Remove the verbose test targets. You can enable this
with make VERBOSE=1 test.

Ensure e2e tests aren't run in the normal test target
as they will fail.

Skip bpfassets tests as they need sudo.

Compile bpfassets tests to a tmpdir and then run them.

Fix assertions in the bpfassets test to skip cpuFreq
given that this isn't populated, and to add more
assertions in the data that comes from `processes`.

Split test run into unit-test, bpf-test and bench
targets.
