Add MFD_NOEXEC_SEAL, MFD_EXEC from Linux 6.3 to bits/mman-shared.h

Linux 6.3 adds new constants MFD_NOEXEC_SEAL and MFD_EXEC.  Add these
to bits/mman-shared.h (conditional on MFD_NOEXEC_SEAL not already
being defined, similar to the existing conditional on the older MFD_*
macros).

Tested for x86_64.
