config: make empty js= omit script tag
According to the cgitrc man page, an empty js= value should cause the script tag to be omitted. But instead, a script tag with an empty URL is emitted. The same applies to css. So, skip emitting a tag if the specified string is empty. Signed-off-by: Samuel Lidén Borell <samuel@kodafritt.se> Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
