stand: remove redundant declarations

These are picked out by the amd64-gcc6 build; time() is declared in <time.h>
and delay() is declared in <bootstrap.h>. These are the correct places for
these in stand/, so remove the duplicate declarations and make sure the
delay() consumer in libefi that depended on the extra delay() declaration
includes <bootstrap.h>.

MFC after:	1 week
