Legally incredibly dubious, particularly since we don't follow it
strictly as policy, and we have git history instead, which does it right.
This is just a waste of time and a cargo cult.

this is also necessary for bundler-1.14.x

i'm still not entirely clear why we ever needed all the fussy software gem
configs or what the build-chef / build-chef-gem infrastructure ever
did for us.  it seems to have been mostly micro-optimization around
building the software gems before bundle installing the project in order
to take advantage of git caching.  i aggressively don't care about that,
this is quite fast enough.  we can install nokogiri and libgecode early
and that should take care of 98% of the build optimization issue.

pulls in chef/omnibus-software#806 and removes iconv from both
nokogiri and ruby.

ruby hasn't needed iconv since 1.9.x and everyone should be using
the Encoding library by now.

nokogiri will lose support for things like Shift-JIS inside of XML
but UTF-8, UTF-16LE/BE, ISO-8851-1(Latin-1), ASCII and "HTML" encoding
are all supported by nokogiri natively.  if users need more they need
to be maintaining their own nokogiri installs and accept the
maintenance costs themselves.

We no longer require the mapfile the Solaris 10u11 and newer.
