tests: avoid spurious failure with older flex (2.5.4)

That old version is unfortunately still relevant, being the one
installed on NetBSD 5.1.

* t/lex-multiple.sh: Use the '-o' option rather than the longer
equivalent '--outfile'.  The latter is not supported by older
versions of flex (e.g., flex 2.5.4).
