fail to fetch proxy user/pw from env variable

[kaisecheng]

http.rb use RUBY_PLATFORM to decide the source of username/ password of the proxy. RUBY_PLATFORM of jruby is java. It blocks jruby user from using proxy with env variable

ruby --version
jruby 9.3.6.0 (2.6.8) 2022-06-27 7a2cbcd376 OpenJDK 64-Bit Server VM 11.0.15+10 on 11.0.15+10 +jit [x86_64-darwin]

reproduce steps

1. export JRUBY_OPTS='-J-Dhttps.proxyHost=user:pw@host -J-Dhttps.proxyPort=3128 -J-Dhttp.proxyHost=user:pw@host -J-Dhttp.proxyPort=3128'
2. ruby -e "require 'net/http'; uri = URI('https://www.google.com'); Net::HTTP.get(uri);"

log

removing ENVIRONMENT_VARIABLE_IS_MULTIUSER_SAFE will solve the issue
