crypto/x509: TestIssue51759 has started to fail on darwin-amd64-10_15

[dmitshur]

As of CL 472295 (which fixed #58791), TestIssue51759 is failing on darwin-amd64-10_15 (only) with:

--- FAIL: TestIssue51759 (0.26s)
    --- FAIL: TestIssue51759/leaf (0.09s)
        verify_test.go:1874: unexpected error: want "invalid leaf certificate", got "x509: “derpkey8dc58100b2493614ee1692831a461f3f4dd3f9b3b088e244f887f81b4906ac26” certificate is using a broken key size"
    --- FAIL: TestIssue51759/intermediate (0.16s)
        verify_test.go:1891: unexpected error: want "SecCertificateCreateWithData: invalid certificate", got <nil>
FAIL
FAIL	crypto/x509	0.640s

See https://build.golang.org/log/530275d3304d16e7558722aa52db917717c82614. (Note that the actual failure is more verbose; I used CL 472097 to produce the shorter one above.)
