Non-matching `dg-output's in testsuite/libffi.complex/cls_align_complex.inc have no effect

Non-matching `dg-output's in testsuite/libffi.complex/cls_align_complex.inc have no effect

[Ilya Yu. Malakhov]

 Because the default precision of `printf ("%f")'s in
testsuite/libffi.complex/cls_align_complex.inc is 6, it would be reasonable to
fix the related `dg-output's as proposed below if they affected the results of
libffi.complex/cls_align_complex_{{,long}double,float}.c tests including this
header at all.

 The reason for why they have no effect is that DejaGnu's `proc dg-get-options'
responsible for picking out the dg-xxx options in a testcase just greps
unpreprocessed .c files. Therefore, no output pattern checks are actually done
in these tests.

 The latter issue also applies to matching `dg-output's in
testsuite/libffi.complex/cls_complex_struct.inc.
