chromium: Update bbappend to version 38.0.2125.101

In this update, the "component-build" packageconfig is no longer enabled
by default. Component builds do use much less RAM on build machines, but
according to Chromium developers, it is not recommended to use these for
anything other than developer builds.

Note that you should still enable component mode if you don't have a
64 bit build machine, or a machine with less than 8 GB RAM.
