libswcale: Fix possible string overflow in test.

In libswcale/tests/swcale.c, the function fileTest() calls sscanf in
an argument of "%12s" on character srcStr[] and dstStr[], which are
only 12 bytes.  So, if the input string is 12 characters, a
terminating null byte can be written past the end of these arrays.

This bug was found by cppcheck.
