fileio: clamp value of windowLog in patch-mode (#2637)

With small enough input files, the inferred value of fileWindowLog could
be smaller than ZSTD_WINDOWLOG_MIN.

This can be reproduced like so:
$ echo abc > small
$ echo abcdef > small2
$ zstd --patch-from small small2 -o patch
previously, this would fail with the error "zstd: error 11 : Parameter is out of bound"
