[PATCH] gc: simplify maintenance_task_pack_refs()

["René Scharfe" <l.s.r@web.de>]

Pass a constant string array directly to run_command_v_opt() instead of
copying it into a strvec first.  This shortens the code and avoids heap
allocations.

This patch is a bit silly because it doesn't actually fix anything, but
I can't resist pointing out the possible code size reduction.  And if
opts becomes used eventually it's probably easier to use the args member
of struct child_process instead of supplying our own strvec.
