Disable Valgrind by default during testing (#3269)

Previously, the configure script automatically enables Valgrind during
testing when the valgrind command is found. However, running tests with
Valgrind is quite slow, so it is better to disable it by default, and
to enable it only when the user specifies the `--enable-valgrind` flag.
