Remove some configure header-file checks that we weren't really using.
We had some AC_CHECK_HEADER tests that were really wastes of cycles, because the code proceeded to #include those headers unconditionally anyway, in all or a large majority of cases. The lack of complaints shows that those headers are available on every platform of interest, so we might as well let configure run a bit faster by not probing those headers at all. I suspect that some of the tests I left alone are equally useless, but since all the existing #includes of the remaining headers are properly guarded, I didn't touch them.
