rc: fix rc script parsing
77e1ccbee3
introduced a bug whereby rc scripts in etc/rc.d and $local_startup failed to parse output from called commands because IFS was set to " " instead of the default " \t\n". This caused parsing of output that contains any whitespace character, such as tabs and newlines, not matching just a space to fail. PR: 249192 MFC after: 3 weeks X-MFC with:77e1ccbee3
