Reformat imath.c macro to remove -Wmisleading-indentation warnings.

Recent versions of gcc whine about the admittedly-completely-illegible formatting of this macro. We've not noticed for a few reasons: * In v12 and up, the problem is gone thanks to 48e24ba. (Back-patching that doesn't seem prudent, though, so this patch just manually improves the macro's formatting.) * Buildfarm animals that might have complained, such as caiman, do not because they use --with-openssl and so don't build imath.c. * In a manual run such as "make all check-world", you won't see the warning because it gets buried in an install.log file. You have to do "make -C contrib all" or the like to see it. I noticed this because in older branches, the last bit doesn't happen so "check-world" actually does spew the warnings to stderr. Maybe we should rethink how that works, because the newer behavior is not an improvement IMO. Back-patch down to 9.2, pursuant to newly-established project policy about keeping out-of-support branches buildable.
