source4/torture: Add SEC_STD_DELETE to enable proper cleanup

basic.maximum_allowed and smb2.maximum_allowed attempt to unlink the
files created by those tests. But the restrictive SD with which they
were created prohibits the deletion inside shares where vfs_acl_xattr
is configured including "ignore system acls". The very same file will
otherwise cause problems while progressing with remaining sub tests.
SEC_STD_DELETE could be the minimum required additional access mask
to successfully delete the file under the said configuration using
vfs_acl_xattr and "ignore system acls" option without loosing the
integrity of the overall test.
