From: Jackie Liu liuyun01@kylinos.cn
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.
