Fix -e option with only one value in qualifier statement

Fix regression introduced by commit v4.5.20-19-g30145dd:
if -e option is used with only one value in qualifier statement,
e.g. 'strace -e trace=open ls', syscall information would not be
printed properly.

* syscall.c (qualify): Remove faulty optimization.
