lib: add report_pass

The assertion macros in the vmx tests only call report() if the test
fails. This avoids a lot of logging (e.g. vmx_ept_access_test_reserved_bits
checks 3460 assertions). However the test runner interprets passing runs
as "skipped" because it looks like no testcases were run. Add a function
called report_pass(), which lets tests report that a test passed without
printing anything to the console.
