Don't use echo -e in run_tests.sh

In one section, the run_tests script attempts to use the -e (interpret
escapes) option to echo.  This option is not portable - for example
the echo built into dash, now the default /bin/sh on several
distributions does not support it and will just echo "-e" literally.

Since we don't actually use any of the escapes that -e enables, this
patch simply removes it.
