stat.2: Clarify description of EOVERFLOW error

The EOVERFLOW error is not only for st_size, but also
inode and block size fields. See glibc source file
sysdeps/unix/sysv/linux/xstatconv.c and kernel source
file fs/stat.c. Also, fix bit/byte confusion
See http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=604928
