misc/mxnet: fix build with clang 19
Clang 19 now implements CWG 96 [1], which requires a template argument
list after a 'template' keyword, resulting in errors similar to:
/wrkdirs/usr/ports/misc/mxnet/work/incubator-mxnet-1.9.1/src/api/operator/numpy/../../../operator/numpy/../tensor/./elemwise_binary_broadcast_op.h:358:18: error: a template argument list is expected after a name prefixed by the template keyword [-Wmissing-template-arg-list-after-template-kw]

This can be done with a REINPLACE_CMD in the post-patch phase.
