shadow install - "install -dv /etc/default" no longer needed

[Justin R. Knierim]

A very little nitpick. When installing shadow, the new version installs a lot more than the old version did.

make[3]: Entering directory `/usr/src/shadow-4.0.16/etc'
test -z "/etc" || mkdir -p -- "/etc"
 /bin/install -c -m 644 'login.defs' '/etc/login.defs'
test -z "/etc/default" || mkdir -p -- "/etc/default"
 /bin/install -c -m 644 'useradd' '/etc/default/useradd'
test -z "" || mkdir -p -- ""

This makes the shadow instructions:

 The -D option of the useradd program requires the /etc/default directory for it to work properly:

install -dv /etc/default

not needed.
