Cast NSInteger to long for formatting as %ld

In https://crbug.com/747643, a new version of Clang produces warnings
when attempting to format NSInteger as %zd (which is normally used for
ssize_t). Acquiesce by casting NSInteger to long and formatting using
%ld.

In the process, I audited all occurrences of %zd in GTM and found that
the remainder were being used to format size_t, which ought to use %zu,
so I’ve corrected those.

I also audited the existing uses of %zu and found them all to be
correct.
