CryptoPkg: Update .gitignore for OpenSSL source masking

Updates .gitignore that masks the OpenSSL source:
1. Remove "Include/openssl" from .gitignore since we needn't duplicate
   openssl headers now
2. Update "openssl-*" to "openssl*", since we use "openssl" instead of
   "openssl-x.x.xx" as main source directory.
