# Execute the given command, removing any Ruby-specific environment

#
# - _ORIGINAL_GEM_PATH
# - GEM_PATH
# - GEM_HOME
# - GEM_ROOT
# - BUNDLE_BIN_PATH
# - BUNDLE_GEMFILE
# - RUBYLIB
# - RUBYOPT
# - RUBY_ENGINE
# - RUBY_ROOT
# - RUBY_VERSION
#
# This will escape Vagrant's environment entirely, which is required if
# calling an executable that lives in another Ruby environment. The
# original environment restored at the end of this call.
#
# @param [Proc] block
# the block to execute with the cleaned environment
