RFR JDK-8071501 perfMemory_solaris.cpp failing to compile with "Error: dd_fd is not a member of DIR."

[Gerald Thornbrugh]

We discussed this option and decided to stay with the legacy prototypes
for JDK8 and JDK9 for now. We will open up an RFE to move to the POSIX
prototypes in the future.

Thanks,

Jerry
