varasm: Fix bootstrap after the .base64 changes [PR115958]

Apparently there is a -Wsign-compare warning if ptrdiff_t has precision of
int, then (t - s + 1 + 2) / 3 * 4 has int type while cnt unsigned int.
This doesn't warn if ptrdiff_t has larger precision, say on x86_64
it is 64-bit and so (t - s + 1 + 2) / 3 * 4 has long type and cnt unsigned
int.  And it doesn't warn when using older binutils (in my tests I've
used new binutils on x86_64 and old binutils on i686).
Anyway, earlier condition guarantees that t - s is at most 256-ish and
t >= s by construction, so we can just cast it to (unsigned) to avoid
the warning.
