tools/e2fsprogs: fix building on a glibc 2.27 host

The e2fsprogs host build fails on a glibc 2.27 host with

make[6]: Entering directory 'build_dir/host/e2fsprogs-1.43.7/debugfs'
        CC create_inode.o
./../misc/create_inode.c:399:18: error: conflicting types for 'copy_file_range'
 static errcode_t copy_file_range(ext2_filsys fs, int fd, ext2_file_t e2_file,
                  ^~~~~~~~~~~~~~~

Backport upstream commit "misc: rename copy_file_range to
copy_file_chunk" 01551bdba16ab16512a01affe02ade32c41ede8a in order to
fix this.
