install-build-deps.sh fixes for Lucid and Chromium OS.

install-build-deps.sh fixes for Lucid and Chromium OS.
Add in two extra libraries needed for building Chromium-for-Chromium OS on a fresh install Ubuntu Lucid 64-bit.  Also, start checking for header differences between the 32-bit and 64-bit packages, adding those headers into the 32-bit cons'ed up package install (on Lucid Lynx, the current libcurl4-gnutls-dev package needs this).  Clean up any leftover symbolic links that point nowhere.  Also take any declared package conflicts and remove them from the Provides line to allow the cons'ed up package to always install (the package derived from libcurl4-gnutls-dev).

I believe there is gyp syntax to say "put this at the beginning of the list".  I
worry this will end up depending on when this block gets evaluated otherwise.
