Merge lp:~cjwatson/libusermetrics/valgrind-optional into lp:libusermetrics

[Colin Watson]

Only require valgrind on architectures where it is available.

This should allow libusermetrics to build on the Ubuntu architectures (arm64 and ppc64el) where valgrind is not currently available.

It seems xnox took the opposite approach, blacklisting arches where valgrind is not available:

Either would technically work, but I think in general positive terminology is better when it's a case of something that has to be explicitly ported to each new architecture; it saves on effort when we introduce new architectures.

The debate doesn't really matter when this is already released / merged. Thankyou for the MR. :)
