Subject: [PATCH] tests/api.c: change RSA keysize from 1024 to 2048 for sp-math
 compatibility, in test_wc_CheckProbablePrime(), test_wc_CheckProbablePrime(),
 test_wc_RsaPSS_Verify(), test_wc_RsaPSS_VerifyCheck(),
 test_wc_RsaPSS_VerifyCheck(), test_wc_RsaPSS_VerifyCheckInline(), and
 test_wolfSSL_DC_cert().
