Update bits/mman.h constants and tst-mman-consts.py for Linux 5.3.
The Linux 5.3 uapi headers have some rearrangement relating to MAP_* constants, which includes the effect of adding definitions of MAP_SYNC on powerpc and sparc. This patch updates the corresponding glibc bits/mman.h headers accordingly, and updates the Linux kernel version number in tst-mman-consts.py to reflect that these constants are now current with that kernel version. Tested with build-many-glibcs.py. * sysdeps/unix/sysv/linux/powerpc/bits/mman.h [__USE_MISC] (MAP_SYNC): New macro. * sysdeps/unix/sysv/linux/sparc/bits/mman.h [__USE_MISC] (MAP_SYNC): Likewise. * sysdeps/unix/sysv/linux/tst-mman-consts.py (main): Update Linux kernel version number to 5.3.
