Andrey Kolkov 02bf3e9970 fix(backups): probe live Kafka topics without a pipe and isolate the scratch file ...

The restore existence check piped the live topic list into `grep -qxF`.
grep exits at the first match, so once the matched topic is far enough from
the end of a list larger than the 64 KiB pipe buffer, the producing printf
takes SIGPIPE, pipefail turns the pipeline into a failure, the `if` reads
false, and a topic that exists is sent to --create, which fails with
TopicExistsException. Read the list from a here-string instead: no pipe, no
SIGPIPE, decided by content rather than list size.

Also make the local metadata scratch file overridable (METADATA_FILE),
like BIN already is, so the bats suite can point each test at its own path
instead of sharing /tmp/kafka-metadata.txt across runs. The Job never sets
it and keeps the default.
