This change updates the tapfile helper to read test output from a file
instead of passig it inline in the SQL INSERT statement.
This fixes an issue with large error output from tests, which breaks
tap_ingest_tapfile():
ci-automation/tapfile_helper_lib.sh: line 31: /usr/bin/sqlite3: Argument list too long
Error observed with the cl.toolbox.dnf-install test, which can generate
8000 lines of output. Fix tested with the same output.
