libdwarf: security 20161021 -> 20161124

/cc #20972.  It seems safe API+ABI-wise:
https://abi-laboratory.pro/tracker/timeline/libdwarf/

Also nitpicks: meta.homepage, etc.

Note: `darwin.dtrace` probably contains an embedded copy of libdwarf,
which I didn't (attempt to) fix.

(cherry picked from commit 4918730)
