check_ethernet: fix quoting of string variables

In https://chromium-review.googlesource.com/1036302, Ben Chan pointed
out several instances of "suboptimal" string variable quoting.
Since this CL is a cherry-pick to an almost "retired" R65 release,
it makes more sense to fix those in ToT (R68).

BUG=none
TEST=sudo apt-get install shellcheck # outside of chroot
     shellcheck check_ethernet.hook
     copied to whirlwind, touch /mnt/stateful_partition/.labmachine,
     issued "ifconfig down" from console to force ethernet to "recovery".
