BUG/MINOR: init: Add missing brackets in the code parsing -sf/-st

The codes tries to strip trailing spaces of arguments but due to missing
brackets, it will always exit.

It can be reproduced with this (silly) example:

$ haproxy -f /etc/haproxy/haproxy.cfg -sf 1234 "1235 " 1236
$ echo $?
1

This was introduced in commit 236062f7c ("MINOR: init: emit warning when
-sf/-sd cannot parse argument")
