[PATCH 4/5] test: Handle Operating System Command escapes in terminal output

[David Gibson <david@gibson.dropbear.id.au>]

Our "old style" test script stuff uses raw terminal output scraped from
tmux.  This might include terminal escape sequences from the shell, or
whatever we run in it: they think they're talking to a terminal emulator
not a script, and they're not entirely incorrect.

In several places we filter out ANSI ESC-[ sequences to make this work.
However, this doesn't include ESC-] "Operating System Command" sequences.
Something I've updated in Fedora 43 generates heaps of these, which break
everything.

Add more hairy regexps to filter these out as well.
