do_cmake:sh: do not set BOOST_J

do_cmake.sh is called by src/script/run-make.sh in configure() function,
in src/script/run-make.sh, BOOST_J is also set if it is not set. so we
can drop the code setting BOOST_J in do_cmake.sh.

this helps to silence the cmake warning like:

CMake Warning:
  Manually-specified variables were not used by the project:

    BOOST_J
