Daniel Xu 1846dd8e3a libbpf: Set MFD_NOEXEC_SEAL when creating memfd ... Starting from 105ff5339f ("mm/memfd: add MFD_NOEXEC_SEAL and MFD_EXEC") and until 1717449b44 ("memfd: drop warning for missing exec-related flags"), the kernel would print a warning if neither MFD_NOEXEC_SEAL nor MFD_EXEC is set in memfd_create(). If libbpf runs on on a kernel between these two commits (eg. on an improperly backported system), it'll trigger this warning. To avoid this warning (and also be more secure), explicitly set MFD_NOEXEC_SEAL. But since libbpf can be run on potentially very old kernels, leave a fallback for kernels without MFD_NOEXEC_SEAL support.
