[Build] Assume new equinox.binaries repo name by default in scripts

[HannesWell]

Because the repository containing the Equinox binaries is now named 'eclipse-equinox/equinox.binaries' its folder is, by default, named 'equinox.binaries' after cloning it.
In order to simplify contributions that name should be assumed by default.

Accordingly rename the property 'rt.equinox.binaries.loc' used in the build to 'equinox.binaries.loc'.

@tjwatson do you have any objections?

When this is submitted we should also adapt the paths in
https://github.com/eclipse-platform/eclipse.platform.releng.aggregator/blob/81db9931a45fdbae03b9128f3cd30a791749d831/.gitmodules#L29-L31

and all other references the releng.aggregator repository.

and all other references the releng.aggregator repository.

This is now done with eclipse-platform/eclipse.platform.releng.aggregator#2128.

Finally the build is green (besides the usual TCK failure), so lets submit this.
