Do not mix test result with progress lines.

This makes parsing of the results easier.  Fixes bug#1400.

* tests/openpgp/defs.inc (progress_cancel, progress_end)
(progress_new): New.
* tests/openpgp/conventional-mdc.test: Use progress functions
* tests/openpgp/conventional.test: Ditto.
* tests/openpgp/encrypt-dsa.test: Ditto.
* tests/openpgp/encrypt.test: Ditto.
* tests/openpgp/sigs.test: Ditto.

The new output style is now:

      > MD5 SHA1 RIPEMD160 SHA256 SHA384 SHA512 SHA224 <
  PASS: sigs.test

or if the test fails:

      > MD5 SHA1
  sigs.test: ooops
  FAIL: sigs.test
