strace.1.in: rewrite conditional parts

The current implementation doesn't work as intended since in case the
condition is false, .ig has no effect and it results in "warning: macro
'end_unwind_opt' not defined".  Rewrite it into something more dumb and
verbose, but hopefully correct.

* strace.1.in (.SH SYNOPSYS, .SS Output format): Prepend each
conditional line with respective ".if" instead of trying to wrap
it in ".ig".
