sysv: Remove the filesystem
Since 2002 (change "Replace BKL for chain locking with sysvfs-private
rwlock") the sysv filesystem was doing IO under a rwlock in its
get_block() function (yes, a non-sleepable lock hold over a function
used to read inode metadata for all reads and writes). Nobody noticed
until syzbot in 2023 [1]. This shows nobody is using the filesystem.
Just drop it.
