Use "deploy" to denote that an element provides the deploy
capability for a ramdisk for tripleo installation purposes.
This will be a 3-part change to enable renaming deploy to
deploy-baremetal so that the generic "deploy" capability can
be used for the provides file, as a dependant change will have to
be made in tripleo-incubator.
The tripleo-incubator change is
I1ff4bb98c99dfe87ccc4fb19767b93e27707d3a7 and that swaps to using
deploy-baremetal in place of deploy for ramdisk creation when using
baremetal.

Since we are using bash syntax in some of the element fragments,
we should make sure we use bash for all of them, so that things don't
break on systems where /bin/sh != /bin/bash.

Ramdisks are now built inside a chroot which is built by the normal
image build process. Doing so improves our independence of the
precise state of the build host.
This fixes bug 1194055.
