tests: avoid write-beyond-end-of-heap buffer
In libgcrypt's "make check" (latest from git), I was surprised to
see the "basic" test fail. Here's a patch:
Avoid scary-looking (with MALLOC_CHECK_=3) "make check" test failure:

Subject: [PATCH] tests: avoid write-beyond-end-of-heap buffer
* basic.c (check_bulk_cipher_modes): Allocate one more byte in
each of the two test buffers. Otherwise, running
"env -i MALLOC_CHECK_=3 ./basic" would abort.
