open-vm-tools: add vm_valgrind.h

To build open-vm-tools with valgrind enabled we need this file.

+ *
+ *      This header incorporates the client requests used by Valgrind
+ *      (http://www.valgrind.org/) to instrument the binary for dynamic
+ *      analysis.
+ *
+ *      Various hints are available to mark regions of memory as accessible,
+ *      inaccessible, defined, undefined, to check the definedness or
+ *      accessibliity of regions of memory, or to run code outside of
+ *      Valgrind's instrumentation.
+ *
+ *      See the Valgrind headers for further information.
+ *
+ *      If USE_VALGRIND is defined, the Valgrind instrumentation macros will
+ *      take effect.
+ *
+ *      If USE_VALGRIND is not defined, the Valgrind instrumentation macros
+ *      will still be available but will have no effect (no-op).
