cron: consume blanks in system crontabs before options
On system crontabs, multiple blanks are not being consumed after reading the
username. This change adds blank consumption before parsing any -[qn] options.
Without this change, an entry like:
- * * * * username -n true # Two spaces between username and option.
will fail, as the shell will try to execute (' -n true'), while an entry like:
- * * * * username -n true # One space between username and option.
works as expected (executes 'true').
For user crontabs, this is not an issue as the preceding (day of week
or @shortcut) processing consumes any leading whitespace.
