Fix a signed overflow error on i686 with GCC 4.7.0

Not sure why this one wasn't showing up on x86_64, but this fixes the
compile on i686.

    diskspace.c: In function 'calculate_removed_size':
    diskspace.c:247:4: error: assuming signed overflow does not occur when negating a division [-Werror=strict-overflow]
    cc1: all warnings being treated as errors
