cross-localedef-native : fixup filesystem check error

compile glibc-locale triger error, the error info
is "cross-localedef-native: /xxx/glibc-locale/2.40+git/
locale-tree/Makefile is on different filesystem than rest
(use -f option to override)." But check the file, find it's
filesystem is same as the rest. Now use the f_type instead of
dev_t to check the filesystem.

Can you format the patch to match the style and also create a PR on
githut for cross-localedef?

Hi Khem，
     I'm glad to do the format and PR. But I need some help. 
This is my first time submitting a patch, and my English is not very good, 
so I might have made some mistakes, but I'm not sure.
     I read https://docs.yoctoproject.org/dev/contributor-guide/recipe-style-guide.html
and https://docs.yoctoproject.org/dev/contributor-guide/submit-changes.html#sending-the-patches-via-email 
to do the format wok,  and do the pacthset test. So can you tell me more details, or give me some Introduction Page 
to help do the format work. 
    And I can read section 4.6 of https://docs.yoctoproject.org/dev/contributor-guide/submit-changes.html#sending-the-patches-via-email to create a PR on github for cross-localedef. I'm right?  
                      Thanks！
