Check chdir() after chroot()

mingetty-1.08 does not check chdir(), chroot() and nice() syscalls return value. Failed called can have security implications. Especially missing chdir() after chroot().
This patch fixes these issues.
Patch provided by GNU/Debian (http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=597382), I made error messages more verbose.
Fix.
