shadow: Make useradd work correctly with --root again

Even if useradd --root <root> is used it would still read login.defs
before doing the chroot() and thus use the one provided by the host
rather than the sysroot.

+Subject: [PATCH] Do not read login.defs before doing chroot()
+
+If "useradd --root <root> ..." was used, the login.defs file would still
+be read from /etc/login.defs instead of <root>/etc/login.defs. This was
+due to getdef_ulong() being called before process_root_flag().
