[LTP] [PATCH 1/1] testinfo.pl: Fix array sort on old perl

[Petr Vorel]

From: Petr Vorel <petr.vorel@gmail.com>

It fixes failure on perl v5.16.3 (Centos 7):
Can't use an undefined value as an ARRAY reference at docparse/testinfo.pl line 427.

Fixes: 824e34034 ("docparse: Sort alphabetically tags in table")
