apps: silent warning when loading CSR files with vfyopt option

When verifying or signing a CSR file with the -vfyopt option,
a warning message similar to the following will appear:

  Warning: CSR self-signature does not match the contents

This happens especially when the SM2 algorithm is used and the
distid parameter is added. Pass the vfyopts parameter to the
do_X509_REQ_verify() function to eliminate the warning message.
