[PATCH hurd] libdiskfs: Support --next-task for filesystems

[Damien Zammit]

This standardises the format of the boot parameters so that
they all use the same parameter --next-task to specify the next
task in the boot order.  It does assume the next task is always exec,
however.  This may not be a problem.
