Removed pushbuild errors.

Problem: rpl_variables_stm.test used a character set and a collation which
are not included on all platforms.
Fix: replace the character set and collation by ones that are included on
all platforms. (rpl_variables_stm does not rely on which character set is
used, the only important aspect is the fact that it changes.)
