Move bounds check into ASN.1 parsing function

`x509_get_attr_type_value()` checks for the presence of a tag byte
and reads and stores it before calling `mbedtls_asn1_get_tag()` which
fails if either the tag byte is not present or not as expected. Therefore,
the manual check can be removed and left to `mbedtls_asn1_get_tag()`, and
the tag can be hardcoded after the call succeeded. This saves a few bytes
of code.
