Fix ASN1_STRING_print_ex with negative integers.

ASN1_STRING and ASN1_TYPE type values almost line up, but not quite.
Negative INTEGERs are not possible in X509_NAME (tag2bit maps INTEGER to
0), but negative ENUMERATEDs are (tag2bit maps ENUMERATED to
B_ASN1_UNKNOWN). See https://crbug.com/boringssl/412 for some notes on
this mess. Either way, the library will freely produce ASN1_STRING
INTEGERs and ENUMERATEDs in non-MSTRING contexts, so get this case
right.
