[PATCH v2 10/10] buildtools/get-test-suites: suppress empty output

[Bruce Richardson <bruce.richardson@intel.com>]

If there are no tests which are not assigned to a test suite, omit the
line printing the non_suite_tests. This avoid having error messages from
meson about test "" not being in any test suite.

Fixes: 25065ef1f6c0 ("test: emit warning for orphaned tests")
