MDEV-16678: Actually ignore #sql-ib tables

Apparently, regular expression operations that remove entire lines
of output do not work with list_files, and hence the adjustments in
commit 1c282d4 were ineffective.

For cat_file (preceded by list_files_write_file) the replace_regex
does work.

For some reason, for suite/parts/inc/partition_crash_exchange.inc
some file names will be lost when using list_files_write_file
instead of list_files.

We use a precise pattern match. dict_mem_create_temporary_tablename()
is generating #sql-ib names followed by decimal digits only.
