Fix strncat/wcsncat
Previously, no checks were done when __n <= __b, but strncat _appends_ after
existing content, making this a overly broad check check. For example, with an
8-byte buffer containing "12345\0", strncat(buf, "ABCD", 4) would have the
check skipped, but the result "12345ABCD\0" is 10 bytes, resulting in an
overflow.
This commit fixes this oversight, and adds a bunch of tests.
