autoconf: Tidy up header includes

Tidy up our list of header includes so it's easier to see what
we're testing for. The list is now one-per-line, in alphabetically
sorted order.

Note that this won't affect our use of the default include set, as
autoconf will already have tested for all of those before it starts
this CHECK_HEADERS run.
