grunt: Mark RW_LEGACY as CBFS

Depthcharge is changing how the RW_LEGACY CBFS is handled for alternate
bootloaders, see https://crrev.com/c/1528550 and
https://crrev.com/c/1530303. This means that RW_LEGACY must be marked as
CBFS in the fmap in order to work. All boards except for kahlee(grunt)
have CBFS marked.

BUG=b:128703316
TEST=Build and ran on grunt along with chromium patches on grunt and was
     able to list alternate bootloader with ctrl+l
