libarchive: Fix OpenSSL crypto library checks for build inside CMake
libarchive's crypto library checks use its `config.h` inside the
`try_compile` project. Since commit ade3b16e63 (libarchive: Use KWIML
to get fixed-size integer types, 2020-06-01, v3.18.0-rc1~33^2),
that header depends on KWIML inside CMake. Add the include directory
for KWIML to the crypto library checks. Otherwise, they always fail
due to not finding the KWIML headers, and libarchive decides not
to link the crypto library.
libarchive has other code besides the hash algorithms that depends on
the crypto library if its ENABLE_OPENSSL option is enabled (which in
CMake is controlled by CMAKE_USE_OPENSSL). It seems to be missing some
conditions to link the crypto library in those cases, and instead relies
on at least one of the above-mentioned checks to pass. If they all
fail, and we are using system curl, we might not link the crypto
library.
Fixes: #23234
