[jumbo] Fix symbol clashes in components/rapport unittests

Follow up to ad2c0dc8c2bca1b767007ac3cacdb8652b566907.

TestLogUploader is defined as both rappor::TestLogUploader and
rappor::(unnamed namespace)::TestLogUploader and could thus be ambiguous
if being present in the same jumbo unit. Add rappor:: qualification in
TestRapporServiceImpl to combat this.

The kTestRapporParameters structure is defined in sampler_unittest.cc
and rappor_metric_unittest.cc. Give these slightly more unique name
(reflecting the test they are for) to avoid this.
