tests: add --use-system-commands

This change allows to use commands from $PATH rather than from
$top_builddir. There two basic use cases:

* check differences between installed and git version
  run.sh --use-system-command --show-diff

* check system binaries by upstream tests (for example tests from
  src.rpm package)
