Subject: [PATCH 2/2] runlatex.sh: Fix while loop condition

After commit 33b93f8258f5 ("qqz: Cross-link questions and answers"),
'make' becomes to terminate prematurely with warning messages such as

>   Latex Warning: There were undefined references
>   Latex Warning: There were multiply-defined labels.

This can be dealt with loosening loop condition in runlatex.sh
which is given to 'grep' command.
Also, This commit increases the iteration max count to accommodate
the required number of 'pdflatex' invocations caused by qqz cross-link.
