common/config: create $RESULT_BASE before dumping kmemleak leaks

In _init_kmemleak() we're touching a check_kmemleak file in
${RESULT_BASE} if ${DEBUGFS_MNT/kmemleak} exists as a marker that we
have to check for kmemleak output after running a test.

In 'check' we're calling _init_kmemleak() at around 60% of the file,
but ${RESULT_BASE} is created later at around 62% of the file,
causing the 'touch' in _init_kmemleak() to fail.

Create the ${RESULT_BASE} just after assigning the default value in
get_next_config()

[Eryu: check for mkdir failure and remove the $RESULT_BASE creation
in check.]
