[LTP] [PATCH 1/1] testinfo.pl: Properly handle NULL

[Petr Vorel]

While at it, add missing comma to the arguments.

Fixes: 946d20bdaf ("metadata: metaparse: Better array parsing.")
Signed-off-by: Petr Vorel <pvorel@suse.cz>

NOTE: if we don't want to have NULL in the docs (see e.g. hugemmap10),
we can simply filer it:

$content .= paragraph(table_escape(join(', ', grep defined, @$v2)));
