dmabufallocator: adds gst_dmabuf_allocator_alloc_with_flags
If we can guarantee the lifetime of the fd is longer than
the memory, we can use DONT_CLOSE flag not to close when release.
But it's not provided in gstdmabuf yet while gstfdmemory does.
For example, in case of using VA-API or MSDK, we would need this api.
Otherwise we should call dup to duplicate the fd.
