Subject: [PATCH v1 3/4] bitmap: Clean up test_zero_fill_copy() test case and rename

Since we have separate explicit test cases for bitmap_zero() / bitmap_clear()
and bitmap_fill() / bitmap_set(), clean up test_zero_fill_copy() to only test
bitmap_copy() functionality and thus rename a function to reflect the changes.

While here, replace bitmap_fill() by bitmap_set() with proper values.
