package/nginx: use /run instead of /var/run

This is a follow-up to 4027ba29f4 ("package/nginx: use /run for
PIDFile"), in which we missed that nginx is still built with /var/run
paths.

This commit changes the compile options to use /run instead of
/var/run for pid and lock file to make it consistent.

Further dropping the passing of the pid option in the service file as
this isn't neccessary. Neither debian nor nginx default .service does
it.
