crypto: fix assertion caused by unsupported ext
    
    `X509V3_EXT_print` can return value different from `1` if the X509
    extension does not support printing to a buffer. Instead of failing with
    an unrecoverable assertion - replace the relevant value in the hashmap
    with a JS null value.
