kern-tools: fix processing for no branch meta-data

Lernel meta-data that has patches, but no branches, can trigger an
error due to no branch specific patch queue.

This error then cascades to more issues since the tools are using
a named file in /tmp to store and display error messages to the
user.

We fix both issues though the following kern tools tweaks:

    scc: use mktemp for consolidated output capture

    To provide useful error messages the tools dump pre-processed
    files and messages to a temporary file. If multiple users are
    doing builds, this means they either race, or can have permissions
    issues.

    By creating the temporary file via mktemp, we avoid both issues.
    (We also make sure to clean these up on exit, or /tmp will get
    polluted quickly).

    patch: do not assume a branch specific patch queue is needed

    When processing input files per-branch and global patch queues are
    generated. If the meta-data has not created any branches in the
    repo, no branch specific queue is required.

    The tools assumed that one is always valid, and hence would throw a
    non-zero exit code and stop processing.

    By testing for a named per-branch queue, we avoid this issue.
