Besides fixing several bugs in the context of the SPANK plugin this PR mainly introduces the utilization of
spank_prepend_task_argv().spank_prepend_task_argv()was introduced in Slurm 23.11 and allows to manipulate the (to be spawned) task'sargvfrom within a SPANK plugin. This makes Spindle's SPANK plugin working again with Slurm 23.11 and above.It seams to me that the SPANK plugin broke once the tweaking of libc's jump table in
spindleHookSpindleArgsIntoExecBE()andinterceptExecForMap()stopped working due to making this table read-only.
