MDEV-15937 Assertion failure 'key->flags & 1' on ALTER TABLE

Browse Source 
While the test case crashes a MariaDB 10.2 debug build only,
let us apply the fix to the earliest applicable MariaDB series (10.0)
to avoid any data corruption on a table-rebuilding ALTER TABLE
using ALGORITHM=INPLACE.

innobase_create_key_defs(): Use altered_table->s->primary_key
when a new primary key is being created.
