bitbake: toaster: unbuilt package dependency formats

[YOCTO 6057]

For a package shown on the package build dependency page, the dependent
packages may be unbuilt packages, as indicated with the dependent
package's size set to -1.  This fix changes the build template to use
the same formatting functions for unbuilt dependent packages as the
include package templates use for unbuilt dependent packages.
