[bug#29058] [PATCH] tests: install: Estimate the installation system disk size.

[Hartmut Goebel]

1500 MiB are too small for a current system, thus use let
system-disk-image estimate the required size.

* gnu/tests/install.scm: (run-install): Pass "#:disk-image-size
  'guess" to system-disk-image.
