swscale/tests/swscale: Fix potential buffer overflow

The field width in a %s directive gives the amount of characters
to read from the input and not the size of the receiving buffer;
the latter must be of course also have space for the trailing \0
which has been forgotten here. The commit adds it (and fixes a
-Wfortify-source warning from Clang).
