file_reader/on_open_expect_fault intermittently fails when test_progs runs tests in parallel, because it expects a page fault on first read. Another file_reader test running concurrently may have already pulled the same pages into the page cache, eliminating the fault and causing a spurious failure. Make file_reader/on_open_expect_fault read from a file region that does not overlap with other file_reader tests, so the initial access still faults even under parallel execution.
