tests/lint: fix test d_cast_init on macppc

On macppc, char == unsigned, which generated the following unintended
warnings:

d_cast_init.c(18): warning: initialization of unsigned with negative
    constant [221]
d_cast_init.c(18): warning: initialization of unsigned with negative
    constant [221]
d_cast_init.c(18): warning: initialization of unsigned with negative
    constant [221]
d_cast_init.c(18): warning: initialization of unsigned with negative
    constant [221]
