nesc 1.3.6

New homepage and package source: the old homepage at sourceforge
is apparently abandoned and there does not seem to be a
replacement. Github seems to be the closest to a homepage that
exists. It hosts the current repository for nesc and tinyos now.

Another change affects the way we build nesc. Up to 1.3.5 the
maintainers released tarballs with some preprocessing already
done, this is not the case for 1.3.6. The result is that we depend
on autoconf and automake and need to call ./Bootstrap.

Closes Homebrew/homebrew#50366.
