opt_dff: fix sequence point copy paste bug
Newer GCCs emit the following warning for opt_dff:
passes/opt/opt_dff.cc:560:17: warning: operation on ‘ff.Yosys::FfData::has_clk’ may be undefined [-Wsequence-point]
560 | ff.has_clk = ff.has_ce = ff.has_clk = false;

Which is correct: the order of whether the read or write of has_clk
occurs first is undefined since there is no sequence point between them.
This is almost certainly just a typo/copy paste error and objectively
wrong, so just fix it.

string is equivalent to "\0", and is 8 bits wide, so that's wrong.
After this commit, a replication operation with a count of zero is
used instead, which is explicitly permitted per 1364-2005 5.1.14,
and is defined to have size zero. (Its operand has to have a non-zero
size for it to be legal, though.)
