media-libs/audiofile: Add security patches

Dropping the system-gtest patch is necessary to make the tests run, as
mentioned here: https://bugs.gentoo.org/680482#c8

The three closed bugs are reported test failures fixed by dropping the
aforementioned patch and a slight repair of src_test. Because we're not
using system gtest anymore, we can drop the test dependency on
dev-cpp/gtest, and by extension the IUSE=test boilerplate.

Subject: [PATCH] Actually fail when error occurs in parseFormat
When there's an unsupported number of bits per sample or an invalid
number of samples per block, don't only print an error message using
the error handler, but actually stop parsing the file.
This fixes #35 (also reported at
https://bugzilla.opensuse.org/show_bug.cgi?id=1026983 and
https://blogs.gentoo.org/ago/2017/02/20/audiofile-heap-based-buffer-overflow-in-imadecodeblockwave-ima-cpp/

When building the library with NDEBUG, asserts are eliminated
so it's better to always check that the number of coefficients
is inside the array range.
