m4ri: add ${makedepends} to m4ri-devel depends
https://github.com/void-linux/void-packages/pull/34004

Description:
@leahneukirchen we missed this, and now m4rie is not building without libgomp-devel.

I think the proper fix is to add libgomp-devel to depends for m4ri-devel, rather than add it to makedepends for m4rie, which is what this PR implements.
