DuplicateHandle test

There seems to be some kind of optimization in native implementation of
DuplicateHandle function. In some cases when DUPLICATE_CLOSE_SOURCE flag is
used output and input handles are identical. Thanks to it a handle stored
inside msvcrt remains valid on windows. DuplicateHandle behavior is identical
on all testbot machines.

Output of attached program, Win7:
in = 0000000B
1: in = 0000000B, out = 00000007, (in==out) = 0
in = 000000C4
1: in = 000000C4, out = 000000C4, (in==out) = 1
in = 000000C4
1: in = 000000C4, out = 000000C4, (in==out) = 1

Wine:
in = 0000001B
1: in = 0000001B, out = 00000027, (in==out) = 0
in = 00000018
1: in = 00000018, out = 00000028, (in==out) = 0
in = 00000018
1: in = 00000018, out = 00000028, (in==out) = 0
