UBUNTU: Sync build-deps with master to avoid future FTBFS

It's purely a fluke that we build with reduced build-deps,
partially because the buildd chroots mistakenly have openssl
installed (this is being fixed), and partially because we
currently have tools disabled, which we should fix.

UBUNTU: Fix up linux-tools -> SRCPKGNAME-tools rename

There were two spots where the linux-tools -> SRCPKGNAME-tools
rename was missed in debian/control, despite it having been
done in rules.d.  Fix this, so the .dsc no longer claims we own
linux-tools, which we don't.
