Vyacheslav Egorov 56ad16f4de [vm] Make VM strict about min required Mac OS X version.
Refuse to initialize VM if current Mac OS X version is below
MAC_OS_X_VERSION_MIN_REQUIRED, which was configured in build
time through mac_sdk_min GN argument.

TEST=tested manually by changing return value of MacOSXVersion
