chromium: Update all channels to latest versions.

Browse source 
This introduces version 31.0.1650.57 as the new version for the stable
channel.

Overview of the updated channels:

stable: 30.0.1599.114 -> 31.0.1650.57
beta:   31.0.1650.34  -> 32.0.1700.19
dev:    32.0.1671.3   -> 33.0.1712.4

This drops the sandbox_userns_30.patch as version 30 is no longer
stable. In addition, we had to patch out some references to /usr/bin/gcc
in the bundled WebKit sources.

Builds are passing and running fine.

commit 41510de6ae32e6161073992bd1243f7f33148a06
Author: aszlig <aszlig@redmoonstudios.org>
Date: Thu May 16 14:17:56 2013 +0200
zygote: Add support for user namespaces on Linux.
The implementation is done by patching the Zygote host to execute the sandbox
binary with CLONE_NEWUSER and setting the uid and gid mapping so that the child
process is using uid 0 and gid 0 which map to the current user of the parent.
Afterwards, the sandbox will continue as if it was called as a setuid binary.
In addition, this adds new_user_namespace as an option in process_util in order
to set the UID and GID mapping correctly. The reason for this is that just
passing CLONE_NEWUSER to clone_flags doesn't help in LaunchProcess(), because
without setting the mappings exec*() will clear the process's capability sets.
If the kernel doesn't support unprivileged user namespaces and the sandbox
binary doesn't have the setuid flag, the Zygote main process will run without a
sandbox. This is to mimic the behaviour if no SUID sandbox binary path is set.
