ruby: improve reproducibility

Find out rbconfig.rb and created.rid from ${B}/.installed.list
and remove build host directories

- For rbconfig.rb, parse it like python's _sysconfigdata.py
[snip rbconfig.rb]
 26   CONFIG["INSTALL"] = 'install -c'
[snip rbconfig.rb]

- For created.rid, it records file created time, just strip ${WORKDIR} prefix.
[snip created.rid]
