Sergei Golubchik 62d1e3bf67 MDEV-23569 temporary tables can overwrite existing files ...

for internal temporary tables: don't use realpath(),
and let them overwrite whatever orphan temp files might've
left in the tmpdir (see main.error_simulation test).

for user created temporary tables: we have to use realpath(),
(see 3a726ab6e2, remember DATA/INDEX DIRECTORY). don't allow
them to overwrite existing files.
