fix portability problem with uselocale(), et. al.

misc/create_inode_libarchive.c uses uselocale(), newlocale(), et. al.
These functions are defined in POSIX.1-2017, which isn't available
everywhere --- including MacOS and Windows.

We don't actually need to use these functions, since mke2fs already
calls setlocale() to initialize to use the default locale.  So there
was no reason to set and restore the locale to use exactly the default
locale.

Fixes: ecfd4dd1217a ("Decouple --without-libarchive and HAVE_ARCHIVE_H")
Fixes: 7e3a4f0a33e9 ("mke2fs: the -d option can now handle tarball input")
