Title: Do not clear ENV config vars

According to the docs it is possible to configure kerl both by using `.kerlrc`
and passing ENV variables from the command-line, i.e.

KERL_INSTALL_MANPAGES=yes ./kerl install

However the ENV vars were being cleared/overriden, so you could only use `.kerlrc`.

This fixes it.
