CHROMIUM: config: enable DM_CRYPT target

The dm "crypt" target is needed for encrypted /var support. Additionally, since the
expected hash alg will be sha256, built it in, and ready future support for sha512
as a module.

BUG=chromium-os:22172
TEST=build, boot amd64-generic, verify target listed in "dmsetup targets"
