shadow: add new recipe 4.1.4.2

(borrow from OpenEmbedded with below tweaks)

Enhance login_defs_pam.sed according to shadow source, to ensuer we don't
leave any unknown definitions in /etc/login.defs when pam is enabled

no need for --disable-account-tools-setuid which is detected upon pam
automatically, and no specific CFLAGS append

move shadow site options to generic site files

adjust indention

RDEPENDS on a list of pam-plugins since they're separately packaged

test with both pam enabled and pam disabled. when pam is enabled, tried
some same tweak with desired effect.
