x11/cde*: Catch up to src bb421be6c117

src bb421be6c117 moved ftime(3) to libutil. This resulted in this
error:

ld: error: undefined symbol: ftime

referenced by getdate.c

libDtCmP_a-getdate.o:(cm_getdate) in archive ../libDtCmP/libDtCmP.a

There are other programs and libraries that also reference ftime(3).
Rather than patch each Makefile.am, add -lutil to LDFLAGS.
