test/extended/router: Dump crypto-policy for FIPS

Update the new tests that use a FIPS-incompatible key to gather and print
out the content of /etc/crypto-policies/back-ends/opensslcnf.config so that
the configured crypto-policy can be examined in case of test failures.

* test/extended/router/certs.go: cat
/etc/crypto-policies/back-ends/opensslcnf.config after each test.
