Commit 006a328ad6be ("util-linux: fix build with ncurses") removed
dependency on BR2_USE_WCHAR, but failed to update the reverse
dependencies of util-linux.

This commit fixes all such reverse dependencies by removing dependency
on BR2_USE_WCHAR as it is not required by package itself.

Changes v1 -> v2:
  - Moved packages, that directly needs wchar or when wchar dependency
    is pulled from other dependencies, into separate patch 2/2 of this
    series.
  - All packages except circus, python-pyzmq are build tested for qemu
    x86 with wchar disabled or br-arm-basic config.
  - circus, python-pyzmq depend on python which essentially depends on
    wchar, so these couldn't build test.
  - gummiboot is failing with i386 related configs without this patch
    as well because stdint.h is not found. That failure isn't related
    to wchar.
  - docker-engine with btrfs support is failing because execinfo.h is
    not found. It doesn't seem to be related as well.
  - BR2_INIT_SYSTEMD depends on glibc toolchain. We explicitly selects
    BR2_USE_WCHAR for glibc based toolchains. So couldn't build test
    this package.
