CryptoPkg: remove global variable 'timeval' from OpenSslSupport.h

The header file OpenSslSupport.h not only defines a type 'struct timeval'
but also defines a global variable 'timeval' of that type. The RVCT
compiler does not merge this definition into a common symbol, resulting
in duplicate definition errors in the final link. So remove the
variable definition.
