dde_rump: fix rump_iso test

The run script did not consider the routing for the environment ROM
sessions for the test-iso component. It routed all ROM sessions -
including the ones for the executable and the dynamic linker - to
fs_rom. The patch also adds the cap quota definitions required since
version 17.05 and fixes a whitespace inconsistency between the test
program and the run script.

Thanks to Steven Harp for reporting!
