It seems the usage of (guix build syscalls) in java.scm and
ant-build-system is solely for 'mkdtemp!'.  Guile 3.0.6 gained
'mkdtemp', so I suppose we can switch to that?

If there are backwards-compatibility concerns it seems possible to
modify these procedures to not need to 'mkdtemp' at all.

I can prepare a patch along these lines, but not sure if we need to
maintain backward compatibility in (gnu packages).

This relationship was added in b0ddbb05729e86ce4efb7eac8909317e16d7bed7
and is possible to trade at a purity cost.
