CMakeLists.txt: synchronize CMAKE_C_FLAGS with diagnostic flags set in autotools-generated Makefile (-Wall -Wextra -Wno-unused -Werror), and fix WOLFSSL_RSA_PSS to add -DWOLFSSL_PSS_LONG_SALT as needed by changes to test_wolfSSL_CertRsaPss() in fb531dacc2 (gating of those changes is also added in this commit).
