Update vim to 8.1.1526, GTK3, 64-bit, and /etc/vimrc

[Mno-hime]

Due to security stuff reported by @AndWac: https://github.com/numirias/security/blob/master/doc/2019-06-04_ace-vim-neovim.md.

Ported to GTK 3, 64-bit, added global /etc/vimrc with changes requested at 10342 which make console experience much better.

As Ruby support requires 64-bit Ruby, which we don't have, I disabled it.

Will update it later to https://github.com/vim/vim/releases/tag/v8.1.1473 where https://github.com/OpenIndiana/oi-userland/pull/5062/files#diff-410f1f87aafda62ff93a766e7117f8b5 was fixed.

Should I merge?

[Mno-hime]

It's slightly controversial as it disables Ruby support (or something). I'll rather ask on discuss ml.

You should be able to enable ruby support now in 64-bit version.

Thanks, it builds ruby-26. One thing I should add to the default vimrc is set mouse=, so mouse click does not enter to insert mode, but didn't have luck with it so far, though it works fine on vim's : "command line".

Should we open illumos-gate issue?

test target is broken:
$ gmake clean test pre-publish
make[3]: *** No rule to make target 'zh_CN.ck', needed by 'check'. Stop
