qt-faststart: Increase the copy buffer size to 64 KB

Copying data in chunks of 1 KB is a little wasteful.

64 KB should still easily fit on the stack, so there's no need
to allocate it dynamically.

qt-faststart: Simplify code by using a MIN() macro

qt-faststart doesn't use the normal libav headers at all since
it's supposed to be a completely standalone tool, so we implement
the macro locally in this file.

qt-faststart: Fix the signedness of variables keeping the ftello return values

These variables are assigned the return values of ftello, which
returns an off_t, which is a signed type. On errors, ftello returns
-1, thus make sure this error return value can be stored properly.
