benchmark: Fix incompatibility with C89 compilers

Browse source 
Initializing arrays using non-constant expressions is not permitted in
C89, and was causing errors when compiling with Metrowerks CodeWarrior
(for classic MacOS) in C89 mode. Clang also produces a warning when
compiling with '-Wc99-extensions':

test/benchmark.c:670:42: warning: initializer for aggregate is not a compile-time constant [-Wc99-extensions]
        const unsigned char *dhm_P[] = { dhm_P_2048, dhm_P_3072 };
                                         ^~~~~~~~~~
test/benchmark.c:674:42: warning: initializer for aggregate is not a compile-time constant [-Wc99-extensions]
        const unsigned char *dhm_G[] = { dhm_G_2048, dhm_G_3072 };
                                         ^~~~~~~~~~

Declaring the arrays as 'static' makes them constant expressions.
