TT#82051 shellcheck fix for console_output() to expand escape sequences

We are using console_output() from within log_info(), which is invoking
`console_output "$*\n"`, so we need to expand the escape sequences
(without interpreting other format specifiers), which is exactly what
"%b" provides in bash.

This is a fixup for previous commit 0dda93ad97
