duktape: add an upstream patch to link the shared libraries against libm

Those shared libraries use math functions like ceil but they didn't have
a DT_NEEDED record against libm.  While this is bad, it didn't cause a
significant issue so nobody cared.  But in Core 14 ceil (and maybe
others) has become a GNU indirect function on at least amd64, then
lacking the DT_NEEDED record can cause a crash as explained by
http://maskray.me/blog/gnu-indirect-function#relocation-resolving-order.

Backport the upstream patch to link against libm.
