Currently the building gives:
 * QA Notice: Package has poor programming practices which may compile
 *            fine but exhibit random runtime failures.
 * ../../../src/solaris/native/java/net/Inet4AddressImpl.c:381: warning: implicit declaration of function 'gettimeofday'
../../../src/solaris/native/java/net/Inet6AddressImpl.c:511: warning: implicit declaration of function 'gettimeofday'

../../../src/solaris/native/java/net/Inet6AddressImpl.c:511: warning: implicit declaration of function 'gettimeofday'

This fixes those warnings by including the needed header.
