util-linux: bump to version 2.30

- Update the "basic set" description to include fincore, which is built
  by default, and remove tailf, which was removed in this version.
- Add configuration options for the new utilities "chmem" and "lsmem".
- Add a patch to revert the assumption that ncursesw headers are under
  /usr/include/ncursesw/ only. That's necessary to have both versions
  for ABI/API compatibility but does not make sense on embedded systems.
- Drop autoreconf, since the patch on term-utils/Makemodule.am is gone.

The patch is a bit drastic but it solves the problem of using ncursews
while we discuss a better solution in the util-linux mailing list.
