Move linux sysroots from chrome/installer/linux to build/linux

Move linux sysroots from chrome/installer/linux to build/linux

The sysroot are generally useful (for example when
cross compiling) and not limited to use in the installer
or official releases.

Another reason to move this is that it would allow other
projects to more easily share chromium's build setup
without depending on chrome/.

Also, rename the install script to simply install-sysroot.
This way the script can keep the same name and support
multiple different debian releases without needing
to duplicate the script (e.g. when we switch to jessie).

Can you copy the owners from c/i/linux/OWNERS to build/linux/OWNERS?

File DEPS (right):

DEPS:532: # Downloads the Debian stable sysroot to build/linux/ if needed.
Wheezy is currently old-stable, BTW.

Can you file a tracking bug for this? Then you can mark other efforts that need
it as blocked on that, there's a good place to follow up at with questions, etc.
