Fixed setupWeakLinking asserting if bluepill is launched without a full executable path

[ksuther]

Pass argc and argv and then rewrite argv so the first argument uses the full path to the executable.

Otherwise running bluepill from a shell will fail because argv[0] will be just bluepill rather than the full path to the executable.

Introduced in #327.

There is a unit test failure: testReportWithAppHangingTestsShouldReturnFailure, ((exitCode == BPExitStatusTestTimeout) is true) failed . I'll kicking off the CI again to see if it is a flakiness issue.

The failure seems like something bazel-related or signing-related:
