Reviewed by Yusuke Suzuki.

This is the patch for Windows bmalloc implementation part 1 of N.

On Windows port, USE_SYSTEM_MALLOC is hard coded and cannot enable by
cmake option USE_SYSTEM_MALLOC=Off. This patch removes the restriction
by removing that code.

Note the default value of USE_SYSTEM_MALLOC on Windows port is still on.
There's no actual effect unless passing the cmake arg explicitly.
