APIv2 tests: lots of cleanup

It's been a while since I last looked at these; some cruft
has crept in, generating noise and hence unreadable test
results. Clean it up:

 * remove pushd/popd in one subtest, replace with 'tar -C'.
   (Also remove confusing quotation marks). This removes
   spurious directory names from output.

 * in like(), show only first line of actual output.
   Some commands ('tree', 'generate kube') produce
   voluminous multi-line output, which is super useless
   and distracting when reading a test run.

 * Recognize that some queries will not generate output,
   e.g. HEAD requests and some POSTs. Deal with that.
   This fixes "curl.result.out: no such file" and "parse
   error" warnings.

 * In cleanup, 'podman rm -a' and 'rmi -af'; this gets
   rid of errors when deleting $WORKDIR. (EBUSY error
   when root, EPERM when rootless).

And, the original reason for poking in here: refactor the
wait-for-port part of start_server() into its own helper
function, so we can use it when starting a local registry
in 12-imagesMore. (Ref: #9270)
