swresample/resample_template: add casts to avoid undefined overflows 
resample_linear can produce overflows with craftet input,
The added casts should have no effect on the binary output or the operations they
just change things to a defined regime

Fixes: signed integer overflow: 2069416960 + 78151680 cannot be represented in type 'int'
Fixes: 472047214/clusterfuzz-testcase-minimized-ffmpeg_SWR_fuzzer-6374046976770048
