patch 9.1.1203: matchparen keeps cursor on case label in sh filetype

Problem:  matchparen keeps cursor on case label in sh filetype
          (@categorical, after 9.1.1187).
Solution: Use :defer so that cursor is always restored, remove checks
          for older Vims, finish early if Vim does not support :defer

fixes: #16887
closes: #16888
