Remove hardcoded /usr/local/bin/ paths from jenkins.sh. This caused the
*-latest tests to fail, as they have the Osmocom binaries in /usr/bin
instead of /usr/local/bin.

Default value "master" of the IMAGE_SUFFIX environment variable can be
changed to "latest" to test the latest stable builds instead of the
nightly ones. Use docker_images_require() to make sure that the required
images are existing and up-to-date before running the tests.

To remove code dup and prepare a change to where logs are written, add
collect_logs() to jenkins_common.sh and call that from each jenkins.sh after
the tests are done.
The 'rm -rf' is already done before a test starts. No need to do that again
after each test.
