Fixes <http://bugs.gnu.org/26462>.
* gnu/packages/patches/icu4c-reset-keyword-list-iterator.patch: New file.
* gnu/local.mk (dist_patch_DATA): Add it.
* gnu/packages/icu4c.scm (icu4c)[replacement]: New field.
(icu4c/fixed): New variable.
* gnu/packages/icu4c.scm (icu4c): Download via sourceforge mirrors. The
previous URL,
http://download.icu-project.org/files/icu4c/55.1/icu4c-55_1-src.tgz,
redirects to sourceforge, which then fails because that redirects to
https and as the original URL didn't start with HTTPS, gnutls wasn't
included in the downloader.
