strip: Don't check target_defaulted in input BFD

The target_defaulted field in BFD is set to true if the target isn't
specified.  After

    strip: Add GCC LTO IR support

the target is set to "plugin" if BFD supports plugin when the target
isn't specified nor default.  Update strip to check the input target,
instead of the target_defaulted field in input BFD.

	PR binutils/33230
	* objcopy.c (copy_object): Add a bool argument, target_defaulted,
	to indicate if the input target isn't specified nor default.
	Check it instead of ibfd->target_defaulted.
	(copy_archive): Add a bool argument, target_defaulted, and pass
	it to copy_object.
	(copy_file): Set target_defaulted to true if the input target
	isn't specified and pass it to copy_archive and copy_object.
	* testsuite/binutils-all/x86-64/pr33230.obj.bz2: New file.
	* testsuite/binutils-all/x86-64/x86-64.exp: Run PR binutils/33230
	tests.
