lib/list_sort: test: use generic random32

Instead of using own pseudo-random generator, use generic linux
'random32()' function.  Presumably, this should improve test coverage.

At the same time, do the following changes:
  o Use shorter macro name for test list length
  o Do not use strange 'l_h' name for 'struct list_head' element,
    use 'list', because it is traditional name and thus, makes the
    code more obvious and readable.
