Fix some glitches in redbean

Browse source 
This change includes a fix to Fetch() where an out of bounds memory read
could happen, when the reverse proxied endpoint omits the content-length
header. This caused a bunch of NUL chars to appear on TurfWar's /statusz
since it wouldn't actually overrun the buffer, and if it did it would've
been caught by MODE=asan builds.
