Resolve conflicts between Win32 headers and OpenSSL

Both some Win32 headers and OpenSSL/BoringSSL defines some
constant macros like X509_NAME. To avoid that clash we have
a wrapper for <wincrypt.h>, crypto/wincrypt_shim.h Use that
one in chrome/chrome_cleaner/os/system_util.h too since
that header might be used close to OpenSSL code.
