[PATCH v2] remote-testsvn: use internal argv_array of struct child_process in cmd_import()

["René Scharfe" <l.s.r@web.de>]

Use the existing argv_array member instead of providing our own.  This
way we don't have to initialize or clean it up explicitly.  Because of
that automatic cleanup, we need to keep our own reference to the
command name instead of using .argv[0] to print the warning at the end.

Signed-off-by: Rene Scharfe <l.s.r@web.de>

The added command pointer makes the patch more complicated, but I think
it still counts as a cleanup.
