pkcs7.c: Use pkcs7_get_version for signerInfo
The function pkcs7_get_version can be used again
when parsing the version of the signerInfo. Both
require that the version be equal to 1. The
pkcs7_get_version function will return error
if the found value is not the expected version
as opposed to mbedtls_asn1_get_int which does not.
