scripts/gdb: replace flags (MS_xyz -> SB_xyz)
Since commit 1751e8a6cb93 ("Rename superblock flags (MS_xyz ->
SB_xyz)"), scripts/gdb should be updated to replace MS_xyz with SB_xyz.
This change didn't directly affect the running operation of scripts/gdb
until commit e262e32d6bde "vfs: Suppress MS_* flag defs within the
kernel unless explicitly enabled" removed the definitions used by
constants.py.
Update constants.py.in to utilise the new internal flags, matching the
implementation at fs/proc_namespace.c::show_sb_opts.
Note to stable, e262e32d6bde landed in v5.0-rc1 (which was just
released), so we'll want this picked back to 5.0 stable once this patch
hits mainline (akpm just picked it up). Without this, debugging a
kernel a kernel via GDB+QEMU is broken in the 5.0 release.
