ext/POSIX/POSIX.xs: Convert do whiles into whiles

I don't know why these are do { ] while's, but with the correct
combination of compile flags (such as -DNO_LOCALE), and/or perhaps
platform, one or the other could be called the first time with nulls, so
they need to be straight while{}s to avoid segfaults.
