8274293: Build failure on macOS with Xcode 13.0 as vfork is deprecated

[omikhaltsova]

I'd like to backport JDK-8274293 to jdk13u for parity with jdk11u.
The same issue is observed on macOS Monterey 12.0.1 while compiling with Xcode 13.0 (--disable-warnings-as-errors is used because it's not the only issue at the moment):

/Users/olgamikhaltsova/projects/jdk13u-dev-fork/src/java.base/unix/native/libjava/ProcessImpl_md.c:445:17: warning: 'vfork' is deprecated: Use posix_spawn or fork [-Wdeprecated-declarations]
    resultPid = vfork();
                ^
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX12.0.sdk/usr/include/unistd.h:604:1: note: 'vfork' has been explicitly marked deprecated here
__deprecated_msg("Use posix_spawn or fork")
^
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX12.0.sdk/usr/include/sys/cdefs.h:208:48: note: expanded from macro '__deprecated_msg'
        #define __deprecated_msg(_msg) __attribute__((__deprecated__(_msg)))
                                                      ^
1 warning generated.

The original patch applied partially and manually because os_posix.cpp doesn't need any fixes due to JDK-8262955 is not included to jdk13u. This patch is absolutely identical to that one applied to jdk11u.
