dependencies: hdf5: mark configtool dependency not-found for cmake build

When hdf5 is built with cmake instead of autotools, it makes a number of
weird changes. What we care about in particular is that h5cc exists but
doesn't work -- it happily ignores -show and tries to compile stuff,
then leaves us with a dependency that has no libraries, and fails when
running `ninja`.
