[PULL 12/17] scripts/: fix some comment spelling errors

[Laurent Vivier]

From: zhaolichang <zhaolichang@huawei.com>

I found that there are many spelling errors in the comments of qemu,
so I used the spellcheck tool to check the spelling errors
and finally found some spelling errors in the scripts folder.
