lib/libc/tests/string: improve memccpy "bounds" unit test
The purpose of the "bounds" test is to check that the function does not
overread the array bounds. The old unit test, copied from the strlcpy()
one, always ensured that we see the character c memccpy() is looking for
in the source array before the array ends. While this is correct for
strlcpy(), memccpy()'s specification does not guarantee that c is
present within the given size limit.
The updated test handles this case better, ensuring that the source
array ends early if c is not supposed to be present.
