run_test.sh is corrected

This patch fixes a problem with run the following commands:

"time <set env> converage run ..."

This command does not work (on altlinux-10 with custom build of PG).

I do not know why it happened and do not know why it was working early.

"<set env> time converage run ..." works without any problems.
