package/google-breakpad: switch to the new git repository

Google-breakpad moved to a new git repository last year and the old svn
repository has been deleted. So, the Buildroot archive mirror is used.

svn: E160013: Unable to connect to a repository at URL 'http://google-breakpad.googlecode.com/svn/trunk'
svn: E160013: '/svn/trunk' path not found
--2016-11-27 10:42:34--  http://sources.buildroot.net/google-breakpad-1373.tar.gz

Swith to the git repository using the git hash corresponding to the
1373 svn revision. But there is an issue with the third parties...
Some of them are not bundled with Google-breakpad or as git submodule.
Even worst, the google-breakpad source code use #include
"third_party/lss" directly, so we can't provide missing third parties
with an external package.

That's why the linux-syscall-support package was added to Buildroot,
it provide the missing linux_syscall_support.h file which is must be
copied to src/third_party/lss/ in the Google-breakpad sources.
