teuthology/misc: Valgrind exits on first detected error.

Valgrind v3.14 brought the `--exit-on-first-error` option
which causes termination of the process on first encountered
error. Although it does nothing for memory leaks, it should
help with pin-pointing e.g. `UninitValue` without imposing
the costly `--track-origins=yes`.
