(FACT-3159) Fix install.rb for Ruby 3.0

When executing this script under Ruby 3.0, the following error is
generated:

/usr/lib/ruby/3.0.0/fileutils.rb:206:in `mkdir_p': wrong number of
arguments (given 2, expected 1) (ArgumentError)

This patch changes install() and makedirs() calls to use the keyword
argument form which is supported at least since Ruby 2.7.
