schannel: fix wildcard cert name validation on Win CE

Fixes a few issues in manual wildcard cert name validation in
schannel support code for Win32 CE:
- when comparing the wildcard name to the hostname, the wildcard
  character was removed from the cert name and the hostname
  was checked to see if it ended with the modified cert name.
  This allowed cert names like *.com to match the connection
  hostname. This violates recommendations from RFC 6125.
- when the wildcard name in the certificate is longer than the
  connection hostname, a buffer overread of the connection
  hostname buffer would occur during the comparison of the
  certificate name and the connection hostname.
