       kconf_check: store some files in tmpdir

       Some file systems, like ZFS, are very slow at appending to existing
       files. Due to Copy-On-Write nature, they create a new copy of a file
       each time we do ">>" in a shell script. This becomes very noticeable
       if shell script does lots and lots of appends, like sanitize_fragment()
       function in kconf_check. On my setup, do_kernel_configcheck task takes
       literally hours to complete.

       To fix this issue, we can store sanitized_list and fragment_errors.txt
       files on tmpfs, which is extremely fast at writing. As most distros
       use tmpfs for /tmp, logical step is to use `mktemp` to create
       temporary files.

       After completing writing to temporary locations, we can move those two
       files back to ${LOGDIR}.

       Also, function 'cleanup' was added to remove temporary files in case
       of abnormal exit.

       With this patch, do_kernel_configcheck task completes in ~2 minutes on
       my setup, which is a great improvement.
