Bug #8183 MERGE and SYM cause wrong SHOW CREATE TABLE

Without this patch, all file elements in info have symlink resolved
pathnames.  This means append_create_info does not  have any way
of showing the correct database name when a symlinked database is used.


myisam/mi_open.c:
  store name (not symlinked resolved) instead of org_name (symlink resolved)
  in info.
