"cros_sdk" is a drop-in replacement of enter_chroot.sh. The only
important difference is in the calling path, specifically that
cros_sdk is in path but has to be called from $(pwd) being inside the
repo checkout, while enter_chroot.sh is called by explicit path.
Invariably, "./enter_chroot.sh" can be replaced, as pwd=src/scripts.
Calling by absolute path can be replaced by first changing directory
anywhere into the repo checkout, and then calling cros_sdk.
