The regression tests are currently hard coded to the semantics of mmap in binfmt_elf

With the recent upstream commit 9f834ec18defc369d73ccf9e87a2790bfa05bf46 the cred used for the mmap changed resulting in test failures. The tests have been patched for this change but it results in the test breaking for everyone using upstream releases against pre 4.8 kernels.
