elisp-common.eclass: Add lexbind cookie to site-init files

Browse Source 
This is needed for individual site-init files to be loaded, since Emacs
from Git now complains about missing lexical-binding cookies.

Drop any initial blank lines when installing site-init files in
elisp-site-file-install. Instead, insert blank lines when concatenating
the files in elisp-site-regen.
