Some Linux platforms have a suitably recent kernel to support AFALG, but
apparently you still can't actually create an afalg socket. This extends
the afalg_chk_platform() function to additionally check whether we can
create an AFALG socket. We also amend the afalgtest to not report a
failure to load the engine as a test failure. A failure to load is almost
certainly due to platform environmental issues, and not an OpenSSL problem.

During Configure we attempt to check the kernel version of this platform
to see whether we can compile the AFALG engine. If the kernel version
looks recent enough then we enable AFALG. However when we compile
e_afalg.c we check the version of the linux headers. If there is a
mismatch between the linux headers and the currently running kernel then
we don't compile the AFLAG engine and continue. This was causing a link
error.

The af_alg engine and associated test were creating warnings when compiled
with clang. This fixes it.

The new afalg test should have a copyright date of 2016. Also an
incorrect buffer was being sent to EVP_CipherFinal_ex when
decrypting.
