Some vulnerability analysis tools look at this 'marketing version'
string to determine the version of OpenSSL library. Keep the actual
version there to make the tools happy. Otherwise they tend to treat
OpenSSL 1.0 to be massively vulnerable.
Since we don't have access to OPENSSL_VERSION from build-libssl.sh,
extract the version from OpenSSL header files.
It is also necessary to set matching minimum SDK version in Info.plist
file of the frameworks. Extract the version and replace it in Info.plist
by pattern.
