httpd: keep the send_l2 flags in bit memory

Browse Source 
The two flags added with the JSON fix sit in data, where internal RAM is
full enough that this branch stopped linking for some toolchains. __bit
puts them in the bit area instead and hands three bytes back to the
stack: SSEG goes from 131 to 134 on SWTGW218AS.
